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
