Concept explainers
To find: whether the lines are parallel, coinciding, perpendicular, or none of these.
Answer to Problem 49E
Perpendicular
Explanation of Solution
Given information:
Let the slope of line
Calculation:
Rewrite the given line equation (1) in the slope-intercept form and find slope value as follows:
On comparing the above equation with
Rewrite the given line equation (2) in the slope-intercept form and find slope value as follows:
On comparing the above equation with
Compare the slopes of both the lines,
Since the slope of line equation (1) is negative reciprocal of line equation (2). Thus, both the lines are perpendicular.
