Answer:

Step-by-step explanation:
You are looking for the point of intersection of these two functions.
Substitution:
- This are now your formulas

- You are going to substitute x, so you can solve for y




- Now you are going to substitute y to find x



- Now lets check if it is correct

So it is true, making (-4 , -5) your point of intersection.
hope it helps
Y= -3x+17
Y-y1= m(X-X11)
-3 is m
5 is X1
2is Y1
Y-2=-3)X-5)
Y-2= -3x+15
Add2
Y=-3x+17
