will medalWhat is the direct variation equation if y varies directly with x and

y = –5 when x = –15?

Answer 1

what formula should you remember when you see *varies directly* ?

Answer 2

im not sure

Answer 3

Do you have notes?

Answer 4

no

Answer 5

@phi

Answer 6

i really need this right

Answer 7

a directly varies with b
should remind you to write down

a= k * b
where k is some unknown number

if you have "y varies directly with x "
what equation should you write down?

Answer 8

nvm im gonna fail anyway

Answer 9

are you saying you can't write down the equation?
a directly varies with b should remind you to write down a= k * b

your problem is the same except with different letters
"y varies directly with x "
what is the equation ?

Answer 10

maybe a few more examples:

W varies directly with Z: W = k Z
A varies directly with V: A = k V

R varies directly with T: R = k T

can you do
"y varies directly with x " ?
