Answer 3

varying directly, means "y" is increasing as "x" changes, so

x = 7, y = 11
x = 8, y = 13
so it's increasing, so "y" is varying directly to "x"

to find the constant of variation, that is \(\bf y = n \cdot x\)

pick a pair from the table and plug them in, solve for "n" like before

Answer 4

say x = 7, y = 11

so \(\bf y = n \cdot x \implies 11 = n \cdot 7\)
