Answer:
The value of y is 3.
Step-by-step explanation:
Given points: P(12,-2), Q(5,-10), R(-4,10) and S(4,y).
We need to find the value of y so that line PQ is perpendicular to line RS.
Slope formula:
Slope of PQ is
Slope of RS is
The product of slopes of two perpendicular lines is -1.
Add 10 on both sides.
Therefore, the value of y is 3.

Answer:
No
Step-by-step explanation:
Rearrange the equations to match the linear y=mx+b
1. 3x + 3y = 9
y = -x +3
2. y = -x + 8
y = -x + 8
Since the two equations have the same slope, they are parallel, not perpendicular.
