Question

Write a scenario that could work for the following line of best fit: y = -0.8x + 5.6. Explain the slope and intercept in this context.

Answer 1

The slope of the line is m=-0.8 and y-intercept = 5.6.

Explanation:

Given : Line of best fit :
`y = -0.8x+5.6`

To find : Write a scenario that could work for the following line of best fit and explain the slope and intercept in this context?

Solution :

Line of best fit :
`y = -0.8x+5.6`

Scenario - Let a person has 5.6 dollars and he spend 0.8 dollars every weekend.

So, The slope is 0.8 but also negative as there is decrements.

The y-intercept is 5.6, the value we obtain from the equation when we set x=0.

So, The slope of the line is m=-0.8 and y-intercept = 5.6.
