Question

What is the constant of proportionality? *

Answer 1

Answer:

9

Step-by-step explanation:

1. The formula to find constant of proportionality is k = y/x, where y = y-coordinate and x = x-coordinate.

2. Let's take the coordinate (1,9) and plug their values into that formula to get the constant of proportionality.

• $k = \frac{(9)}{(1)}$
• $k = 9$

Therefore, the constant of proportionality is 9.
