Answer:

A. y = -8x + 80

Explanation:

Take two points from the best fit line (2, 64), (6, 32)

Find the slope:

[tex]\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points[/tex]

[tex]\sf \rightarrow slope \ (m) : \dfrac{32-64}{6-2} = -8[/tex]

Find the equation:

[tex]\sf y - y_1 =m(x - x_1 )[/tex]

[tex]\sf \rightarrow y- 64 = -8(x - 2)[/tex]

[tex]\sf \rightarrow y = -8x + 16 + 64[/tex]

[tex]\sf \rightarrow y = -8x +80[/tex]
