Answer:
m = -3/2
Step-by-step explanation:
To find the slope of the representation, use the slope formula: 
I'll pick (-4, 9) and (-2, 6) in this instance.
Therefore, the slope of the representation is -3/2.
Answer:
TU = 2 (HD)
Hence, TU = 80
Step-by-step explanation:
line formed by joining 2 mid points of a traingle = 0.5 times of length of 3rd side.
40:10 is equivalent to 2:0.5
Think of it as a fraction. (40/10) We can then reduce that. So we divide 10 by 10 and what we do to one side we have to do to the other so we divide 40 by 10 and we get 4/1 we can then divide both sides by 2 and get 2/0.5 or 2:0.5 :D
