Question

Use point-slope form to write the equation of a line that passes through the point

(9,8) with slope – 2.

Answer 1

y - 8 = -2(x - 9)

Explanation:

Given the slope, m = -2, and the point, (9, 8):

Let (x₁, y₁) = (9, 8)

slope (m ) = -2

We can substitute these values into the following point-slope form:

y - y₁ = m(x - x₁)

y - 8 = -2(x - 9) ⇒ This is the point-slope form.
