y=-5x-7

For this question we will use the slope intercept form equation, because we are provided with the slope and the y-intercept.

The slope intercept form equation is
`\large\textsf{y=mx+c}`. In this formula m denotes the slope and c denotes the y-intercept.

Since we have both m and b, we can stick them into the formula. Upon doing this we obtain

`\twoheadrightarrow\sf y=-5x+(-7)`

`\bullet` Simplify

`\twoheadrightarrow\sf y=-5x-7`

`\bullet` Great job! We found the equation

Answer 2

y=(-5x)+(-7)

Explanation:

The equation for slope is y=mx+b

so you would say -5x as the mx in the equation and -7 as the u intercept.
