Question

Which equation best models the data in the table below?

Answer 1

A) y = 0.76x + 3.72

Explanation:

Data points: (2, 5) and (11,12)

Slope:

m=(y2-y1)/(x2-x1)

m=(12-5)/(11-2)

m=(7)/9

m= 0.78

Slope-intercept:

y - y1 = m(x - x1)

y - 5 = 0.78(x - 2)

y - 5 = 0.78x - 1.56

y = 0.78x + 3.44

Choice A is the closest to this solution
