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.
