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]
