Week #12 Relations and Functions

To find the X intercept you make Y equal to 0. Essentially you want to isolate X in order to find what it is equal to. When finding the Y intercept it is nearly the same thing except you replace X with 0 in order to isolate Y to find what it is equal to.

When you write the X intercept in ordered pair form you but the X value first followed by Y (which should be 0).

ie:            (-4, 0)

Same with if you’re writing out the Y intercept in ordered pair form, you put the Value as 0 and plug in the Y value.

ie:               (0, 13)

When you have these two points you can begin to place them on a graph.
