There's probably a mistake in the problem; as written the answer is none of the above.
We have slope from the first two points of (4-2)/(0-4) = -1/2 and a y intercept from the second point of 4 so
f(x) = (-1/2) x + 4
maybe that's the third choice; forgot the fraction bar.

70 - 60 = 10
10 / 2 = 5
Thus 65
I think the answer is the third one
