Answer:
Slope is -5/3
Step-by-step explanation: when you look at the graph, the line is descending meaning it will be a negative, so we can eliminate the answers that are positive leaving us with 2 options. Then we have to do rise/run, you figure that out by counting how many points the line goes up and to the right or left, and intersects with the line
Function F goes in the first one, G goes in the second one, and H goes in the last one. Hope this helps :)

-625
foil
first foil (20 + 15i)(15i - 20) to get
(20 * 15i) + (20 * (-20)) + (15i * 15i) + (15i * (-20))
= (300i) + (-400) + (225) + (-300i)
combine like terms
combine the i terms together to get
(300i) + (-400) + (225) + (-300i)
300i - 400 + 225 - 300i
= -400 + 225
substitute -1 into i^2
remember that i = so = -1, and substitute this into -400 + 225i^2
-400 + 225i^2
= -400 + 225(-1)
= -400 -225
= -625
