Complementary angles add up to 90 degrees. We know that AXB is 20 degrees, and AXB is complementary to CYD and FZE. So CYD and FZE are 90-20, so each angle is 70 degrees
CYD = 70 degrees
FZE = 70 degrees
CYD + FZE = 70 + 70 = 140
A) y=5x+8

Answer:
I like saying rise over run because it helps me remember that rise means how many units you move up or down from point to point which on a graph would be a change in the y values. Also that run means how far left or right you move from point to point which on the graph would mean a change of x values.
Answer:
75%
Step-by-step explanation:
100-25 = 75
Step-by-step explanation:
the slope is always the ratio "y coordinate charge / x coordinate change" when going from one point on the line to another.
so, when going from (-2, 1) to (4, -3)
x changes by +6 (from -2 to 4).
y changes by -4 (from 1 to -3).
therefore, the slope is
-4/+6 = -4/6 = -2/3
