Answer 1

equation for a direct variation is
\[\huge\rm y = kx \] where k is constant of variation
replace x and y by their values solve for k

Answer 2

5=k(-3)?

Answer 3

yes right solve for k

Answer 4

how?

Answer 5

k(-3) can be written as -3k
to cancel -3 from right side divide both side by -3
y = -3k divide both side by -3

Answer 6

can write it like u did i n the previous problem it made more sense too me that way

Answer 7

k = ?
