Answer: 
Step-by-step explanation:
<u>Given information</u>
Point B = (-2, -4)
Reflection line: y = x
<u>Concept:</u>
When reflecting over the line y = x, the position of y and x in the original coordinate switches places.
This is because it is " y = x ", assuming that they could interchange
<u>Find the coordinate of Point B'</u>
Original (x, y) = (-2, -4)
Point B' = (x', y') = (y, x) =

7 unit to the left, means it is 7 less than -1.
-1-7 = -8
Ans: -8
a triangle adds to 180 degrees
we have 90 and 40 so the hypotenuse is 50 degrees
