Question

Sara wanted to gather data about the cost of local gyms in her area. She plotted the data and determined that the average gym costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 10x + 30. Identify and interpret the y-intercept in this model.

Answer 1

Answer:

y-intercept is 30

Step-by-step explanation:

Given the model  $y = 10x + 30.$ comparing this model to the equation of a straight lines  we can get the y- intercept

$y = 10x + 30\\\y= mx+c$

The y- intercept is 30 which is the constant factor and it describes to us about the one-time registration fee of $30.

Answer 2

The y-intercept in this model for the average gym costs is 30.

What is the y-intercept?

In a linear equation, the y-intercept can be interpreted as the constant. It is the value that does not change with the number of months a person goes to the gym. The y-intercept can also be referred to as the fixed cost. In this question, the y-intercept is 30.
