Answer:
P - Q = - 11b² + 8b - 4
Step-by-step explanation:
P - Q
= - 4b² + 6b - 9 - (7b² - 2b - 5) ← distribute parenthesis by - 1
= - 4b² + 6b - 9 - 7b² + 2b + 5 ← collect like terms
= - 11b² + 8b - 4

BTW, brainliest would be greatly appreciated, I only need one more before I advance, thanks!
Also, I may have done something wrong, please tell me if it's incorrect!
M = (y2 - y1) / (x2 - x1)

m = (5- -4) / (-2 - 3)
m = 9/-5 = - 9 / 5
