Question

A hardware store manager reviews data that shows how well a new product is selling over an 8-week period. The data can be modeled by the equation y = - 13.9x + 103 , where x represents time in weeks and y represents the number of units of the product left in stock. what does-13.9 represent

Answer 1

-13.9 represents the slope

It is the number of units of the product left in stock per week

The negative value shows it decreases per week

Explanation:

Here, we want to state what the value -13.9 represents

Generally, the equation of a straight line can be represented by the equation

y = mx + c

where m is the slope

In this case, -13.9 represents the slope of the model

The slope is calculated by dividing a change in y by a change in x

With respect to the question, the slope here represents number of units of the product left in stock per week
