Step-by-step explanation:
Given :
re - writing the equation , we have
we need to find the value of a and b for which -2<x < 4 , this means that the roots of the quadratic equation are -2<x < 4.
The formula for finding the quadratic equation when the roots are known is :
- sum of roots(x) + product of root = 0
sum of roots = -2 + 4 = 2
product of roots = -2 x 4 = -8
substituting into the formula , we have:
, which could be written in inequality form as
comparing with , it means that :

Answer:
The answer to your question is slope = 0; y = -2
Step-by-step explanation:
Data
A (-2, -2)
B (2, -2)
Process
1.- Calculate the slope
m = (-2 - (-2)) / (2 - (-2))
m = ( -2 + 2) / (2 + 2)
m = 0/4
m = 0
2.- The equation of the line is
y - y1 = m(x- x1)
y - (-2) = 0(x - (-2))
y + 2 = 0
y = -2
