Answer:
c) (-2, 6)
Step-by-step explanation:
Subtracting the second equation from the first gives ...
(y) -(y) = (x^2 +3x +8) -(2x +10)
0 = x^2 +x -2 . . . . . simplify
0 = (x -1)(x +2) . . . . factor
Solutions for x are 1 and -2. The corresponding y-values are ...
y = 2{1, -2} +10 = {2, -4} +10 = {12, 6}
The solutions are (1, 12) and (-2, 6). The only matching choice is (-2, 6).

Answer:
3/2
Step-by-step explanation:
Pick two points on the graph
(-1,2) and (3,8)
We can use the slope formula
m= ( y2-y1)/(x2-x1)
= ( 8-2)/(3 - -1)
= (8-2)/(3+1)
= 6/4
= 3/2
