Answer:
The answer to your question is below
Explanation:
Data
A = (10, 10)
B = (22, 2)
C = (30, 8)
D = (12, 20)
Process
From the graph, I conclude that I must determine the slope of AB, BC, CD and AD.
Formula
slope = m = (y2 - y1) / (x2 - x1)
1.- Find the slope of AB
m = (2 - 10)/ (22 - 10)
m = -8/12
m = -4/6
m = -2/3
2.- Find the slope of BC
m = (8 - 2) / (30 -22)
m = 6 / 8
m = 3/4
3.- Find the slope of CD
m = (20 - 8) / (12 - 30)
m = 12 / -18
m = -6/9
m = -2/3
4.- Find the slope of AD
m = (20 - 10)/ (12 - 10)
m = 10/2
m = 5
