Its a multiplication by -3 on each term, so I think you're gonna answer is by r=-3, maybe?
First multiply all terms by z
8-z^2=4z
Then order into standard form
-z^2-4z+8=0
Multiply the equation by -1
z^2+4z-8=0
Plug into quadratic equation
-4±√16-4(-8)
-4±√48
(-4±4√3)/2
-2±2√3
Final answer: z=-2± 2√3
Answer:
slope = 0
Step-by-step explanation:
