Question

What is the constant of proportionality in the following equation? Write your answer as a single rational number.

y=1.3x

A) 1.3

B) 0.77

C) 2.0

D) 0.65

Answer 1

The constant of proportionality in the equation y = 1.3x is 1.3, which is the factor that directly relates y to x in a linear relationship.

Step-by-step explanation:

The question is asking to identify the constant of proportionality in the equation y = 1.3x. The constant of proportionality is the multiplier that directly relates one variable to another in direct proportion. In this equation, the constant that relates y to x is 1.3. Therefore, for every unit increase in x, y will increase by 1.3 units. This is characteristic of a linear relationship between two quantities in a proportional manner.
