To find: equation of line that passes through the point
Answer to Problem 30CR
Explanation of Solution
Given information: Line passes through the point
Formula used: According to slope intercept form, equation of a line is given by
According to point slope form, equation of a line that passes through point
Calculation:
Consider the equation
This equation is in slope intercept form
Compare the equation
So, slope of the line is
Now use the fact that if two lines with slopes
Let
As the required line is perpendicular to the line
Put
Also, the line passes through the point
The equation of the line is
Put
