Answer:

16. [tex]y=7x[/tex]

17. [tex]y=0.5x[/tex]

18. [tex]y=3x[/tex]

19. [tex]y=2x[/tex]

Step-by-step explanation:

Equation is [tex]y=kx[/tex] where k is a constant of proportionality.

16.

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

So, equation is [tex]y=7x[/tex]

17.

[tex]\frac{y}{x}=\frac{1}{2}=\frac{2}{4}=\frac{2.5}{5}=\frac{3.5}{7}=\frac{1}{2}=0.5[/tex]

Equation is [tex]y=0.5x[/tex]

18.

[tex]\frac{y}{x}=\frac{6}{2}=\frac{9}{3}=\frac{15}{5}=\frac{18}{6}=3[/tex]

Equation is [tex]y=3x[/tex]

19.

[tex]\frac{y}{x}=\frac{4}{2}=\frac{8}{4}=\frac{14}{7}=\frac{18}{9}=2[/tex]

Equation is [tex]y=2x[/tex]
