1. Does the equation represent a direct variation> If so, find the constant variation.

5x = -3y (1 point)

a. no

b. yes; k = -5/3

c. yes; k = 5/3

d. yes; k = -3/5

Could you help?

Answer 5

That's Andrews question in case it wasn't clear. He sent it to me in a message.

Answer 6

thanks @TreeFarmer :)

direct variation is given as \(\sf \large y=kx\)
where k is the constant.

since the equation that you provide us shows a direct proportinality, then it is a yes.
now, to get the k, divide both sides by -3, what will you get?

@andrewfaught look here:


so from the above, what will be the value of k?
