Predict the interest earned after 12 years.


129

135

120

144

Answer 1

`x=12, so\\y=4.5 * 12+75\\y=129`

Answer: 129

Answer 2

A

Explanation:

If the best fit for the data is y = 4.5x + 75, we simply want to plug 12 in for x and solve for y:

y = 4.5 * 12 + 75 = 129

The answer is A.

Hope this helps!
