Question

Write the equation of the line with slope 8 and passes through the point ( - 9, - 7)

Answer 1

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
