Answer:
-4.625, -4 8/11, -4 4/5, -5.2
Step-by-step explanation:
-4 8/11 = -4.72727272723
-4 4/5 = -4.8
Absolute value is always positive, unless there is a negative sign outside of the lines
Given points (9,5) = (x1, y1) & (9, -3) = (x2 , y2)
Slope = y2 -y1/ x2 - x1
= -3-5 /9-9
= -8/ 0
As the denominator is zero the slope is ND (not defined)
