Answer:


y=-3x-8

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.

Explanation:

y=-3x+b

Slope intercept is: y=mx+b

m=the slope, b= y intercept

Make each variable contain a value using the point given

  • -8[y]=-3×3[x]+b

It should look like this:

  • -8=-3•3+b

Solve for b

  • -8=-9+b

1=b

Now you have your b value to plug into your final answer

  • y=-3x+1
