Answer:

The answer is y = -5x + 24

Explanation:

To find an equation of a line when given the slope and a point we use the formula


y - y_1 = m(x - x_1)

where

m is the slope

( x1 , y1) is the point

From the question we have


y - 9 = - 5(x - 3) \\ y - 9 = - 5x + 15 \\ y = - 5x + 15 + 9

We have the final answer as

y = - 5x + 24

Hope this helps you
