linear has 1 as highest exponent
D has x^2
D is not linear
18. find slope
(y2-y1)/(x2-x1)=(-1-2)/(0-4)=-3/-4=3/4
y=3/4x+b
B is answer
Answer:
+ 9x + 8 = 0
Step-by-step explanation:
First, we have to simplify this quadratic equation:
(x+2)^2 + 5(x+2) - 6 = 0
x^2 + 4x + 4 + 5x + 10 - 6 = 0
x^2 + 9x + 8 = 0
1 - 9
2 -28
3 54
4 -100
5 -60
6 0
7 49
8 -135
9 -96
10 300
11 0

Hope this helped☺☺
It's a linear function with a slope 0.
It's a horizontal line (look at the picture).
