Answer:
y = 8
Explanation:
Given N(-3,-7), O(-4,-2), P(1, -7), and Q(-2, y), you want to find y such that NO ║ PQ.
Graph
When we plot the points, we see that point O is 1 unit left and 5 units up from point N. Point Q is on a line 3 units left of P, so it will need to be 3×5 = 15 units up from P in order for PQ to have the same slope as NO:
y = -7 +15 = 8
The value of y is 8; the point Q is (-2, 8).
