[B] y + 5 = 5(x + 7)
[C] y - 10 = 5(x + 4)
<h3>Explanation:</h3>
<u>slope</u>(m) = y2 - y1/x2 - x1
- - 5 - 10/- 7 + 4
- - 15/- 3 = 5.
<u>Point slope form to find the equation</u>:
- y - y1 = m(x - x1)
- y - 10 = 5(x + 4)
- y - 10 = 5x + 20
- y = 5x + 30
Answer:
a and b are relative on maxima interval x =-4,x=0
