Concept explainers
a.
To find:
The slope of the line using three different pairs of points on the given line. What conclusion can you draw from your results?
a.
Answer to Problem 39E
The slope of line passing through each pair of points is
Explanation of Solution
Given:
A graph:
Calculation:
First of all, we will find slope of line passing through points
Now, we will find slope of line passing through points
Finally, we will find slope of line passing through points
We can see that slope line passing through each pair is same. Therefore, the slope is same between any points on astraight line.
