The graph below shows a proportional relationship between y and x. What is the constant of proportionality, y/x?

Step-by-step explanation:

We can find the constant of proportionality by finding the value of y when x = 1.

y = 3.5 when x = 1

The constant of proportionality, y/x, is 3.5/1 or just 3.5.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
