To Find: Whether the line
Answer to Problem 21SGR
The lines are perpendicular to each other and the graph is shown in Figure 1
Explanation of Solution
Given:
The given coordinate is
Calculation:
Consider the slope of the line AB is,
The slope of the line
Consider the relation between both the slope is
The graph for the two lines is shown in Figure 1
Figure 1
Thus, from the graph it is clear that the lines are perpendicular to each other.
