Answer:
-2/5
Step-by-step explanation:
You can find this by examining how to get from one point to the other. If you're going from a orange point on the left to one on the right you have to go down 2 units and over 5. That means you do -2 on the y axis and +5 on the x axis. So, with rise over run that equals -2/5.
3 (-3^2 × 1^5) + 4 (-3 - 8)^2
3 (9 × 1) = 27 + 4 (121) = 484
27 + 484 = 511
