<PRE><B>Question 82362</B>
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( 300, 200, -6, 5, -15, 15, 4x+5, 4x-5, -4x+5) }}}
:
Do you understand what we are doing here now? </PRE>
