Answer:
r = 4
Step-by-step explanation:
You need to use the slope formula to solve for r.
1. Write out the equation using slope formula
(-7 - 1)/(r + 4) = -1
2. Multiply both sides by r + 4
-8 = -r - 4
3. Add 4 on both sides. Optionally, use the reflexive property of equality.
-r = -4
4. Multiply both sides by -1
r = 4

Step-by-step explanation:
16m^4 - n^4
= (4m^2 + n^2)(4m^2 - n^2)
= (4m^2 + n^2) (2m + n)(2m - n)
