Suppose y varies directly as x, and y=16 when x=8. what is the equation that relates to x and y

Answer is below

Step-by-step explanation:

Use the equation , where k is the constant of variation

Substitute the new values of x and y into the equation

   Divide 16 by 8 to find k

2 = k

If this answer is correct, please make me Brainliest!

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
