Question

Answer 1

Answer:

see explanation

Step-by-step explanation:

given that x and y are proportional relationships , then

y = kx ← k is the constant of proportionality

divide both sides by x

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

using corresponding values of x and y from each table to find k

first table

k = $\frac{10}{1}$ = 10

second table

k = $\frac{20}{4}$ = 5

third table

k = $\frac{15}{2}$

fourth table

k = $\frac{4}{1}$ = 4
