Answer:
6
Step-by-step explanation:
The first thing you need to do is find the slope. You calculate this by doing the formula, which is y2 - y1/x2-x1. Your answer ends up being (2-4)/(-2-2) which is 1/2. You plug it in to find your equation, which is y = 1/2x+3. Now plug in 6 from the 3rd point, and you get 3+3 which is 6, which is y.
