Answer:

y = -5x + 1

Explanation:

The point-slope form of the equation of a line: y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.

m = -5

(2, -9) ⇒ x₁ = 2, y₁ = -9

So:

y - (-9) = -5(x - 2) ← the point-slope form of the equation

y + 9 = -5x + 10 {subtract 9 from both sides}

y = -5x + 1 ← the slope-intercept form of the equation
