Answer to Problem 22PPE
As the line of fit is not nearer to the original value of stopping distance
Explanation of Solution
Given information:
The stopping distance at 90mi/hr is 584 ft.
As the line of fit is not nearer to the original value of stopping distance because of which the value has a large difference .
Conclusion:
As the line of fit is not nearer to the original value of stopping distance
(d)

Answer to Problem 22PPE
Slope and y-intercept increases.
Explanation of Solution
Given information:
(90,584) are placed on the previous graph.
When we put the coordinates (90,584) on the graph than the slope and y intercept will increase.
Conclusion:
Slope and y-intercept increases.
