Question
This graph shows a proportional relationship.

What is the constant of proportionality?

Enter your answer as a decimal in the box.

Answer 1

Answer:

$0.3$

Step-by-step explanation:

we can find slope of the line using the formula,

$m = \frac{ (y₂ - y₁) }{ (x₂ - x₁) } \\ m = \frac{6 - 1.5}{20 - 5} = \frac{4.5}{15} = 0.3$

The constant of proportionality, which is also the slope of the line, is 0.3.
