How to find the x intercept of an equation in slope intercept form?
The slope- intercept form of an equation is the equation of an upward-sloping line in a coordinate system with the horizontal axis represented by the independent variable and the vertical axis by the dependent variable.
The equation of an upward-sloping line is written as: where is the independent variable and is the dependent variable. This might seem similar to the previous question, but it’s actually quite a bit trickier. The two graphs have different scales, so you can’t just use the methods you used before.
First, use the calculator to determine the equation for the line on the graph. In the calculator window, press “Equation”, then set the first variable to “y”, the second to “x”, and the third to the value of � There are three methods for finding the x-intercept of an equation in the slope-intercept form.
The first method is to solve the equation for the variable and plug it in. The second method is to graph the equation and find the intersection of the two graphs. The final method is to graph the equation and use the calculator to find the intersections. All three methods work well, so choose the method that works best for you.
How to find
There are two ways to find the x- intercept algebraically or graphically. Algebraically, you can solve the equation for the x value where the slope is zero – that is, where the line with a negative slope crosses the x-axis, or where the line with a positive slope crosses the x-axis.
Graphically, you can pick any two points on the line, and then connect them with a line segment. If the line passes through the point where you started, To find the x-intercept of an equation in slope-intercept form, you need to solve the equation for the x-value.
This is most often done by taking the natural logarithm of each side of the equation. However, you can also use a calculator. The equation should be in the form (y = m*ln(x) + b).
Using your calculator, set the x-value equal to one (1), the x-value for which you want When you use a function graphing calculator, you can use the Graph: slope-intercept function to find the line’s x-intercept. You will need to set the line to be in slope-intercept form. That is, enter the equation in the form (y = m*ln(x) + b). Then enter the x-value for which you want to find the x-intercept.
The calculator will return the x-intercept.

How to find the x intercept of an equation in slope intercept form with variables?
If you have two variables on either side of the equal sign, it can be a little harder to find the x-intercept. Fortunately, there are many ways to accomplish this. If you have a calculator handy, you'll want to use the square root function; otherwise, you can use the Pythagorean Theorem.
Similar to the previous method, you can use the inverse of the coefficient to find the value of x that gives you a vertical line passing through the point where the line is tangent to the curve. Using the equation for a line in slope-intercept form, you have the following equation: Using your calculator, find the inverse of the coefficient (the value will be in the parentheses) of the variable in the equation, denoted 𝑝.
Put the value of 𝑝 in as a variable in your equation. The answer will be the x-intercept of this line.
How to find the x intercept in slope intercept form?
To find the x intercept, first set the x-coordinate equal to zero. Then, find the value of the constant term in the equation. Then, add the value of the constant term multiplied by the coefficient of the variable term that equals zero. The x-coordinate of the line is the sum of the zero value of the variable term and the value of the constant term.
The slope of a line is the change in the value of one variable as the change in the value of the other variable. The easiest way to understand this is to use an example. Let’s say you want to find the equation of the line that has a slope of 12 when the line passes through the point (3, 5).
We’ll use slope-intercept form. First, we know that the slope of a line is equal to the rise over the run. The To find the x-coordinate of the line’s intercept, set the x-coordinate equal to zero. The variable term is the independent variable and the constant term is the dependent variable.
Set the x-coordinate to zero. The result will be the value of the constant term. The x-coordinate of the line’s intercept is the sum of the value of the constant term multiplied by the coefficient of the variable term that equals zero.
Doing this will provide the
How to find the x intercept of a linear equation in slope intercept form with variables?
The x-intercept is the point at which the line passes through the origin. If you have two lines that cross each other, you can find the x-intercept of each line by solving the simultaneous equations that represent those lines.
The first line is represented by the equation and the second line is represented by the equation If these two lines cross at the x-axis, then their x-intercepts are equal to the solutions of the two lines when you solve them. In If you have variables in your equation, plug in the values for each variable you have for each of the points.
If your graph is in slope-intercept form, you should be able to find the x intercept by using the point that is farthest from the origin (usually point B). Doing this gives you the equation of the line. Once you have your equation, you can use the calculator to find the value of x, which is your x intercept.
To solve the equation you will plug in x values for each variable. Using the calculator, determine the point on the graph that is farthest from the origin. This point is usually point B. Using that point as your B value, plug it in to your calculator and solve your equation. Voila! You will have your x intercept.
