Answer:

A. y = -3x + 5

Explanation:

Use any two points to find slope, let's use (-2, 11) and (4, -7):

slope m = (y₂ - y₁) / (x₂ - x₁)

= (-7 - 11) / (4 - (-2))

= -18 / 6

m = -3

Use above slope and any one point to find y-intercept, let's use (10, -25):

y = mx + b

-25 = -3(10) + b

-25 = -30 + b

b = 5

Use m and b above to form equation of line:

y = mx + b

y = -3x + 5
