Answer:
y=3x-10 (perpendicular)
y=-3x+9 (parallel)
Explanation:
perpendicular means that the slope is opposite, the opposite of -1/3x is 3x
to find the y intercept, you plug in the points into the equation
2=3(-4)+b
2=-12+b
-10=b
y=3x-10
parallel means that the slope is the same
you do the same thing as before
3=-3(2)+b
3=-6+b
9=b
y=-3x+9
