How to Find X and Y Intercepts on a Graph

Description

This video is a tutorial on how to find x and y intercepts when graphing an equation. It is shown how to continue on and graph the problem. This video provides several example problems.

Overview

Finding x and y intercepts is a simple process if the graph is in front of you, but what if you need to find the intercepts in order to graph the equation? An x-intercept is the point where the line or curve intercepts the x-axis, and is expressed as (x,0). A y-intercept is the point where the line or curve intercepts the y-axis, and is expressed as (0,y). Because you know that when you are solving for an intercept, the other variable is 0, this makes it quite easy to solve for. In a normal graphing equation, there are two variables, an x and a y. To solve for an x-intercept, set the y value equal to 0 and solve for x. To solve for a y-intercept, set the x value to 0 and solve for y. These are your intercepts.
