Answer:

y = 9x + 65

Explanation:

To find the equation of the line 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 the slope is 8 and the point is ( - 9 , - 7)

Substitute the values into the above formula and solve for the equation

We have


y + 7 = 8(x + 9) \\ y + 7 = 9x + 72 \\ y = 9x + 72 - 7

We have the final answer as

y = 9x + 65

Hope this helps you
