1. 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.

3. "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
