Answer to Problem 48SGR
Explanation of Solution
Given:
Year | Ticket cost ($) |
Concept Used:
The slope intercept form is:
Where,
Slope:
Calculation:
Consider;
Year:
Cost of ticket:
Now, take the data points as:
Now, the slope is calculated as:
So, the slope intercept eq. can be written as:
Now, need to put
So, the final slope-intercept form is written as:
Now, the scatter plot of the data points and its line of fit eq. is drawn as:
Conclusion:
Hence, the scatter plot and the line of fit is drawn as above.
b.
