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.

What is an example of an X-intercept?

To find the x-intercept of a line of the form y = mx+b, substitute y = 0. Example: To calculate the x-intercept of any line for example the line y = 2x−4, put y = 0 in the equation of a line.
