Concept explainers
(a)
To explain: the linear function appear to be positive or negative.
(a)
Answer to Problem 38E
The y -intercept of the graph of linear function appear to be negative.
Explanation of Solution
Given:
Consider the graph shows two points that lie on the graph of a linear function
Calculation:
Draw the line joining the two points on the graph.
As from the graph line is a cut the y axis below the x axis.
So, the y -intercept of the graph of linear function appear to be negative.
Conclusion:
Therefore, the y -intercept of the graph of linear function appear to be negative.
(b)
To estimate: the coordinates of the two points and use your estimates to confirm your answer in part (a).
(b)
Answer to Problem 38E
The estimate of the point coordinates are confirm.
Explanation of Solution
Calculation:
Estimate the coordinates of the points
From the graph the coordinates of the points are
Now, to confirm the estimate of the point coordinates, use these points and find the slope
Now, use the slope
Add 4 on both sides
Now, from the equation it is clear that the y -intercept is negative
Conclusion:
Therefore, the estimate of the point coordinates are confirm.
