Triangle abc is similar to triangle def. using the image below, prove that lines bc and ef have the same slope. you must show all of your work to receive credit.

1. find the coordinates of b, c, e and f
b(-2,4)
c(1,1)
e(4,4)
f(6,2)

2. use the formula:
m=y2-y1/x2-x1

3. slope of bc
m=1-4/)
m=-3/3
m=-1

4. slope of ef
m=2-4/6-4
m=-2/2
m=-1

5. so both of the line segments have the slope of -1, have a nice day : d

Idon’t feel like doing the math but you need to do 2.24 divided by 7
