Answer 1

do you know the equation for direct variation ???

Answer 2

no I haven't learned the lesson in class yet :/

Answer 3

\[\huge\rm y = kx \] this equation u have to use for direct variation

Answer 4

now replace x and y by their values and solve for k
k is constant of variation that you have to find first

Answer 5

use first x and y values so plug that into the formula then solve for k
