Answer:

y = -3x+17

Step-by-step explanation:

1. Find the change in y corresponding to the change in x. In this case x is changing by +3 and y is changing by -3. That is your m in y=mx=b.

2. y= -3x + b

To find b substitute a set into the equation. I used 4 and 5.

5= -3(4) +b

3. 5= -12 +b ,add  12 to both sides.

17= b

4. y = -3x+17
