Question

determine whether y varies directly with x. if so, find the constant of variation k.
-4y=8x+16

Answer 1

it does and just solve for y

and you will get it in y=mx+b

m would be your k i think.

Answer 2

-4y=8x+16
y = -2x - 8
so y = - (2x + 8)..

since its negative, its inversely proportional...

Answer 3

so would my k be 2? or 8...

Answer 4

2 your m

Answer 5

i am not sure.. i guess, it should be 2...

Answer 6

thanks for the help!!

Answer 7
