to solve for y in terms of y just set the equation equal to y. Then divide everything by the coefficiant of y.
#1) 2x+7=y (already correct)
x-3=(2/3)y (move y by itself)
(x-3)/(2/3)=y (divide by 2/3)
-12x + 3y = 48
add 12x to both sides
3y = 12x + 48
divide all terms by 3
y = 4x + 16
-1/4y - x = 0
start as above: solve for y
add x to both sides
-1/4y = x
multiply all terms by -4
y = -4x
Now plug in 3 values for x (such as -1, 0, and 1) and find the value for y for each. The three resulting (x,y) pairs are ordered pairs.
