Hi there! The answer is -2.
We can find the slope of a formula by using the following formula:

x2 and y2 don't mean squared, but the x and y coordinate of our second point.
First we need to find two points on the line. Ijn this particular case we have (-3, 3) and (1, -5). Now we can fill in the formula.

Therefore, the third answer is correct.
~ Hope this helps you!
A = 1/5
d = T2-T1
d = 1/10 - 1/5
d = 1/10 - 2/10
d = - 1/10
T4 = 1/5 + 3(-1/10)
= 1/5 - 3/10
= 2/10 - 3/10
= - 1/10
It would take 12.6 gallons
