How do you graph and find the x-intercept?

Great Question! Working with x and y intercepts can get confusing. The x-intercept is the point on the line where the line crosses the x- axis. This means when the value of y is equal to zero. Therefore, this point will lie somewhere along the x axis and will be (x-intercept, 0). The easiest way to find and graph such a point, is to take the equation ( which you may be given, or may have calculated based on the slope and a point on the line), then plug in 0 for y, and solve to find x. Good luck!
