To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x. You can also use the graph of the line to find the x intercept. Just look on the graph for the point where the line crosses the x-axis, which is the horizontal axis.
We can apply regular methods to solve a quadratic equation and calculate the value of x-intercepts. x=2 and x=1 are the two roots of the equation. It means that the graph is crossing the x-axis at two different points.
The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.
The x-intercept (s) is (are) a point (s) where the graph intersects the x-axis. To find the x-intercept of a function, we will just substitute y = 0 in its equation and solve for x value (s).
Finding Intercepts From an Equation. X Intercept: where the graph of an equation crosses the x-axis. Y Intercept: where the graph of an equation crosses the y-axis. To find the intercepts: When you want the x intercepts (x,0): Set y=0 then solve for x. When you want the y intercepts (0,y):
Learn how to find the x-intercepts and y-intercepts of a Linear Function and Quadratic Functions. Solve for x and y intercepts and learn to plot them in the Cartesian Plane.
The general rule for finding the x-intercept or intercepts of any function is to let \(y = 0\) and solve for \(x\). This may be somewhat easy or really difficult, depending on the function. Let’s look at some examples to see why this may be the case.
The x-intercept is the point where the graph cuts the x-axis, whereas y-intercept is the the point at which the graph cuts the y-axis. How to find the y-intercept of a line using the equation? To find the y-intercept, simply put $x = 0$ in the equation of the line and solve for x.

The x-intercepts of a function are the points at which the function is equal to 0, or, using typical function notation, f(x) = 0 (also y = 0). Thus, given the equation of a function, setting the function equal to 0 and solving for x will yield the x-intercept(s) of the function.
