Question

Can somebody please check my work?

Answer 1

which one

Answer 2

Triangle ABC is similar to triangle DEF. Using the image below, prove that parallel lines have the same slope. You must show all of your work to receive credit.

Answer 3

slope of AB=-6/0
slope of DE=-3/0
***both slopes are undefined

slope of segment AC=1
slope of segment DF=1
proof: Y2-Y1/X2-X1
2-8/-11-(-5)
-6/-11+5
-6/-6
=1
***AC=slope of DF since AC is parallel to DF

slope of BC=0/6
slope of EF=0/3
***both slopes are undefined

Answer 4

Your good.

Answer 5

Yes, but the last one, they are =0 , not undefined

Answer 6

but isn't the 0 undefined in graphing since there is no slope? @OOOPS

Answer 7

it's NOT no slope, it is slope =0

Answer 8

Ohhh ok. tysm!!
