Question
How would you graph an equation like x+y=4 or y-1=-1x-2?
I know you have to change the form, i just don't remember how to do it.

remember all you need to draw a straight line is 2 points, the intercepts are 2 good points to use
I just showed you in a previous point how to find those intercepts
x+y = 4
let x = 0 --->y = 4 or the point (0,4)
let y = 0 ---> x = 4 or the point(4,0)
piece of cake!!!
y-1 = -x - 2
x+y = -1
do this the same way
