Answer 1

Answer:

C on Khan Academy. :)

Step-by-step explanation:

Answer 2

Answer:

C

Step-by-step explanation:

In a proportional relationship the constant of proportionality k is

k = $\frac{y}{x}$

Check this ratio for each of the values

A

$\frac{7.5}{5}$ = 1.5 , $\frac{19.5}{13}$ = 1.5 , $\frac{33}{23}$ = 1.4347.... ← Thus not A

B

$\frac{9.5}{8}$ = 1.1875 ← Thus not B

C

$\frac{12}{8}$ = 1.5 , $\frac{13.5}{9}$ = 1.5 , $\frac{27}{18}$ = 1.5

Thus the table with k = 1.5 is Table C
