-4p^2 - 9p + 2 ezzzzzzz just switch the signs bruhhhh
M=(y2-y1)/(x2-x1)
=[-1-(-4)] / (3-1)
=(-1+4) / 2
=3/2
D -9 because it has a -3 and its going to be the same - sign
Step-by-step explanation:
9 = a7 + b
-2 = a9 + b
b = 9-7a and b = - 2-9a
9 - 7a = - 2-9a
2a = - 11
a = - 5.5
b = 9 - 5.5*7 = - 29.5
y = -5.5x - 29.5
