Answer:

Explanation:

We need to find the slope first, and we'll use the formula rise/run.

6 - -9/ -3 - 5 = 15/-8.

Our slope is -15/8.

Now, we need to find the y-intercept, which is b.

y = mx+b.

m is the slope, so y=-15/8x+b

Now, let's replace x with 5 from that point and replace y with -9 from that same point.

-9 = -(15/8)(5) + b

-72/8 = -75/8 + 3/8

So, the equation is y= -15/8x + 3/8
