To Write: An equation of line in slope intercept form that passes through point and is perpendicular to line
Answer to Problem 14PT
An equation of line in slope- intercept form is
Explanation of Solution
Given information:
Line passes through point and is perpendicular to line
Concept and Formula Used:
Slope intercept formwhereis slope andis intercept.
Point slope form of a line:
Perpendicular lines: If lines are perpendicular then the product of their slope is
Calculation:
The required line is perpendicular to First find the slope of given line by comparing with
The slope of line is
Let the slope of required line be ‘m’. As the required line is perpendicular to
Therefore, product of slopes is
The required line passes through and having slope Using point slope form of equation of line
Conclusion:
An equation of line in slope- intercept form is
