Answer:
D 1 and -1
Step-by-step explanation:
divided by 8
(x+1)(x+1)=0
so x=+-1
Answer:
The lines are parallel.
Step-by-step explanation:
The first line is
In slope-intercept form, this line has equation:
The second line is
In slope-intercept form, the line has equation:
The slopes of the two lines are the same (m=1)
however, the y-intercepts of these lines are different (-1) and (+1) respectively.
The first choice is correct.
The two lines are parallel and hence will never intersect.
