Question 398262
-2y = 2 - x
y has to be positive, multiply both sides by -1 and you have
2y = x - 2
divide both sides by 2, (x is understood to be 1x)
y = {{{1/2}}}x - 1
or we could just write it
y = .5x - 1; this is the y=mx+b form, the slope is 1/2, or .5
:
Choose two values for x and find y, to get your points
x=4
y = .5(4) - 1
y = 2 - 1
y = 1
First point: 4, 1
and
x = -4
y = .5(-4) - 1
y = -2 - 1
y = -3
Second point: -4, -3
;
:
plot these two points, join with a straight line, should look like this:
{{{ graph( 300, 300, -6, 6, -6, 6, .5x-1) }}}
:
If we do this correctly, the slope will take care of itself
 you can see it rises 1 unit for each 2 units of run
