Answer:
(-1,-1) and (4.1).
1+1
slope of the line: m= ------- = 2/5
4+1
the slope of the perpendicular line: -5/2 and point (-1,3)
(y-3) = -5/2(x+1)
The reflection is happening over the x axis (horizontal axis)
Any y coordinate that is positive turns negative, and vice versa
For example: (1,2) ---> (1,-2)
In general, the rule is (x,y) ---> (x,-y)
So the answer is choice C
