Answer:

y = 4x + 17

Explanation:

So the general form of the equation is y=mx + b, where m is the slope and b is the y intercept.

The problem gave you the slope = 4.


Substitute that into the general equation:

y= 4x + b

Now let's substitute that point (-6, -7) into the equation and we can solve for b, the intercept.

-7 = 4(-6) + b

-7 = -24 + b

-7+24 = b

17 = b

We know the intercept now, so substitute it back into the equation.

y = 4x + 17

You can double check that it's correct with your provided point.

y = 4*-6 + 17

y = -24 + 17

y = -7 ====>>>> and that's exactly the y that we were given in the problem so you know that this equation is correct.
