Concept explainers
To rotate: The line by given degree and find the equation of the resulting image.
Answer to Problem 30PPS
The equation of image about the x intercept is
Explanation of Solution
Consider the line.
The x intercept of the line is,
Rotate the given line about the point
The image will be perpendicular to the line with same x intercept.
Thus, the equation of line is,
The y intercept of the line is,
Rotate the given line about the point
The image will be perpendicular to the line with same y intercept.
Thus, the equation of line is,
Therefore, the equation of image about the x intercept is
