Step-by-step explanation:
The slope (m) is given by ...
m = (y2 -y1)/(x2 -x1)
Filling in the given values, we have an equation we can solve for r.
-3 = (-4 -8)/(r -2)
r -2 = -12/-3 . . . . . multiply by (r-2)/-3
r = 6 . . . . . . . . . . . add 2
Answer:
D
Step-by-step explanation:
note that (f + g)(x) = f(x) + g(x) , thus
f(x) + g(x)
= - 3 + 3x² + x - 6 ← collect like terms
= 3x² + x - 9 → D
