Question 398262: this is a hard question to put in words, but i have a math equation that looks like this -2y=2-x
i set it up like this y=mx+b
so -2y=2-x and i divide the whole thing by two
i then get y=1 but i dont know how to divide the x
and to graph it after i divide by two i use x as zero and y as what
my assingment calls for two points of each and im not sure if i drop the run over rise and use the next number and just add or subtract what ever the equation asks for. i need to get a slope on the graph please help me

-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 = 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:

:
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
