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 co
1 answer:
Answer:
The slope of the line is m=-0.8 and y-intercept = 5.6.
Step-by-step explanation:
Given : Line of best fit :
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 :
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.

Answer-
The exponential model best fits the data set.
Solution-
x = input variable = number of practice throws
y = output variable = number of free throws
Using Excel, Linear, Quadratic and Exponential regression model were generated.
The best fit equation and co-efficient of determination R² are as follows,
Linear Regression
Quadratic Regression
Exponential Regression
The value of co-efficient of determination R² ranges from 0 to 1, the more closer its value to 1 the better the regression model is.
Now,
Therefore, the Exponential Regression model must be followed.
