Question

Write the direct variation equation for the following: y varies directly with x and y = 60 when x = 10

A. y = 1/6x
B. y - -6x
C. y = 6x
D. y = -1/6x

Also please explain :)

Answer 1

@jrn1007 help?

Answer 2

ok so this question states when x=10 y=60 so we can write this equation differently and say that in order to get 60 for y we need to do something to our x value, either multiply divide it

Answer 3

@jrn1007 so the answer is A?

Answer 4

well if you plug in 10 for x in equation A what would you get out for y?

Answer 5

1.666667 @jrn1007

Answer 6

right! but we want to get 60 out for y

Answer 7

so the answer is C? because 6 * 10 = 60? @jrn1007

Answer 8

Exactly!

Answer 9

@jrn1007 thanks so much!

Answer 10
