'run' is distance x direction changes

'rise' is distance y direction changes

slope='rise'/'run'


for ABC

'run' is 11-3 or 8

'rise' is 10-0=10

slope=10/8=5/4=1.25 (dunno if your program wants fraction or decimal)


for DEF

'run' is 19-15=4

'rise'=20-15=5

slope=5/4=1.25


they are equal because the 2 triangles are similar (congruent means exactly the same but they are different sizes)

Answer:

1 in

8 in 3 because 8^3 is 512 ( 8 x 8 = 64 x 8 = 512)

27 in because 3^3 is 27 ( 3 x 3 = 9 x 3 = 27)

64 in because 4^3 is 64 ( 4 x 4 = 16 x 4 = 64)
