Answer: 
and 
is a right angle .
Step-by-step explanation:
Given : A reflection is a transformation that maps point Q in a figure over a line, AB, such that for point C at the intersection of AB and QQ'.
We know that reflection creates a image equidistant from the line of reflection.
Thus,
Also in reflection , a line drawn from the point is perpendicular to the line of reflection.
Therefore, is a right angle
Answer:

Answer:
3/1 is the slope.
Step-by-step explanation:
Slope formula: y2 - y1/x2 - 1
Plugging in the given values, we get:
-9 - (-6)/3-4
-3/-1
Two negatives cancel each other out, so:
3/1 is the slope.
