Answer:

16. y=7x

17. y=0.5x

18. y=3x

19. y=2x

Step-by-step explanation:

Equation is y=kx where k is a constant of proportionality.

16.

\frac{y}{x}=\frac{10.5}{1.5}=\frac{14}{2}=\frac{24.5}{3.5}=\frac{35}{5}=7

So, equation is y=7x

17.

\frac{y}{x}=\frac{1}{2}=\frac{2}{4}=\frac{2.5}{5}=\frac{3.5}{7}=\frac{1}{2}=0.5

Equation is y=0.5x

18.

\frac{y}{x}=\frac{6}{2}=\frac{9}{3}=\frac{15}{5}=\frac{18}{6}=3

Equation is y=3x

19.

\frac{y}{x}=\frac{4}{2}=\frac{8}{4}=\frac{14}{7}=\frac{18}{9}=2

Equation is y=2x
