(7a + 10b) - (4a - 6b)
(7a - 4a) + (10b - (-6b))
3a + (10b + 6b)
3a + 16b

<em />
Step-by-step explanation: <em>When you plug it into the graphing calculator, you get that exact graph.</em>
Y = mx + b
m = slope. Find b
Y = 22x + b
Plug in the point
-4 = 22(2) + b
-4 = 44 + b, b = -48
Solution: y = 22x - 48
