The x-intercept of a graph is the x-coordinate of the ordered pair where the graph intersects the x-axis. An intercept occurs at a point on the graph where the y-coordinate is 0. The x-intercept can be given as a value or as an ordered pair.

The y-intercept of a graph is the y-coordinate of the ordered pair where the graph intersects the y-axis. A y-intercept occurs at a point on the graph where the x-coordinate is 0. The y-intercept can be given as a value or as an ordered pair.

You can use algebra expressions or graphs to determine the intercept value. With algebra, you have an equation that you fill in the opposite variable of the one you are trying to determine as 0 and then solve the rest of the equation. Example like so… , , , Separate the x variable, Divide by 5, and Voila!

*With the intercepts, using algebra to determine the value gives you the exact value, whereas using graphs gives an estimated value.*
