Question

1. determine if the values in the table are proportional (yes) or not (no).

x | y
18 | 6
30 | 10
48 | 16
54 | 18

Explanation:

Step1: Check first pair

Calculate $\frac{Y}{X}$ for (18,6): $\frac{6}{18}=\frac{1}{3}$.

Step2: Check second pair

For (30,10): $\frac{10}{30}=\frac{1}{3}$.

Step3: Check third pair

For (48,16): $\frac{16}{48}=\frac{1}{3}$.

Step4: Check fourth pair

For (54,18): $\frac{18}{54}=\frac{1}{3}$.
All ratios are equal, so proportional.

Answer:

yes
