Write answer in slope intercept form (3,-8); slope= -3
Slav-nsk [51]

Answer:

y=-3x-8

Step-by-step explanation:

The slope intercept form is y=mx+b.

The "mx" is the slope; which in this case is -3. So -3x.

The "b" is the y-intercept, which is this case is the -8 because it is the 2nd number in the coordinate point.

This is why the answer is y=-3x-8.
