Answer to Problem 4E
The slope of the linepassing through the given points is
Explanation of Solution
Given:
A graph:
Concept used:
Calculation:
Upon looking at our given graph, we can see that as x increases the y also increases and line is going uphill, so slope of the given line is positive.
Now we will find the slope of line.
Let point
