How would you graph
y=4x+5, y=4x-5, and y=-4x+5
:
Plot each equation; using x = -2 and x = +2 find y:
y = 4x+5 as an example
:
x | y
--------
-2 | -3
+2 | 13
:
Do the same with the other two equations, your graph should look like this:
+graph%28+300%2C+200%2C+-6%2C+5%2C+-15%2C+15%2C+4x%2B5%2C+4x-5%2C+-4x%2B5%29+
