Answer:
f(x) = 20x + 10
Step-by-step explanation:
(0 , 10) ; (3 , 70)
Slope = 

y- intercept = 10
f(x) = mx + c
= 20x + 10
I believe the answer is b:)

Answer:
F' = (7, 6)
R' = (-1, 7)
I' = (-2, -5)
O' = (6, -6)
Step-by-step explanation:
The rule of reflection over the y-axis is, (x, y) ---> (-x, y). So change all the x values into the opposite signs. So the -7 of F would turn into just 7, the 1 of R would turn into -1, the 2 of I would turn into -2, and -6 of O would turn into just 6.
