find the variation constant and an equation of variation where y varies directly as x and y=35 when x=5 the variation constant is k=

This is easy 35 would go into 5 7 times so the answer would be variation constant is 7. this is a two part qustion the 2nd part is the same as the first but u add the x its called the equation of variation.

equation of variation is 7x.

Reiny,
"y varies directly as x "  y = kx , where k is a constant
sub in the given: x=5, y = 35
35 = 5k
k = 7
so y = 7x
