Answer 2

Option C) is correct.

Explanation:

Sandra enters a pumpkin growing contest each year.

currently her pumpkin measures 36 inches in circumference.

She models the weekly growth for her pumpkin with the equation

y = 2x + 36 which is similar to Y = mx + C

"C" represents "Y - intercept" which is at x = 0

measurement on Y axis x = 0 signifies the starting date of the contest.

and for x + 0 ⇒ y = 2 × 0 + 36 = 36

Which is starting size of the pumpkin.

Therefore, Option C) is correct.
