To Write: An equation of line in slope intercept form that passes through point

Answer to Problem 11PT
An equation of line is
Explanation of Solution
Given information:
Line passes through point
Concept and Formula Used:
Slope intercept form
Point slope form of a line:
Parallel lines: If lines are parallel then the slopes of lines are equal
Calculation:
The required line is parallel to
Now, find the slope of given line by comparing it with
The slope of line
Let the slope of required line be ‘m’. As the required line is parallel to
Therefore, the slope of required line is equal to slope of
The required line passes through
Conclusion:
An equation of line is
