Question

Please Help! Select the line parallel to 8x-20y=40
a.) y=-4/5x+5
b.) 20x+8y=16
c.) 4x-10y=51
d.) y=5/4x+3

Answer 1

The answer I get is y=2/5x-20

Answer 2

I'm unsure how to change the format to fit the options I have...

Answer 3

8x-20y=40
so first you want it as y=mx+b
so you subtract -8x on both sides to get -20y=-8x+40
then side -20 on both sides.

which later becomes y=2/5x-20

it would be c because when you work on that equation you also get 2/5 which is you looking for. they have to have the same mx value

Answer 4

@Asevilla5 Can you show me how to work the equation to get it to that format?

Answer 5

alright for C, its not in y=mx=b
so for 4x-10y=51
subtract 4 on both sides to get -10y=-4x+51
then divide by -10 on both sides to get y=2/5+51/-10
for the 51/-10 you can just leave it like that since it is already simplified or you will get a mixed number that you don't want

Answer 6

Alright that makes more sense =) Thanks I really appreciate it !

Answer 7

no problem =)
