Answer:
Step-by-step 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
