Question

Find the equation of the line whose slope is -3 and which passes through the point (5,-2).

Answer 1

y = -3x + 13

Explanation:

We can use the the point slope form of an equation for this:

y - y1 = m (x - x1)

Replace the y1, x1, and m variables with what we were given:

y - (-2) = -3 (x - 5)

Distribute

y + 2 = -3x + 15

Combine like terms

y = -3x + 13
