Answer:
(-3,-6) and (-3,2)
Step-by-step explanation:
A line with an undefined slope is vertical. In this case it must have x coordinates equal to -3
I'll give you a hint
20) Add 56 to both sides
23) Add 1.5 to both sides
Also, as a AP Calc BC student, laziness doesn't really help get a good job soo...
First find the equation of y.

Find the slope m.
.
Pick one point, I'll pick (-3, 9). Insert coordinates in equation then compute n.
.
The equation of a line y is:
.
The perpendicular line
is same like the normal line except its slope m becomes:
.
The equation of a perpendicular bisector is thus:
.
Hope this helps.
