To find: the equation of line that passes through the point
a .
Answer to Problem 78E
Explanation of Solution
Concept Used:
Slope intercept form of equation of line is
Point slope form of equation of line is
Consider,
The lines of the form
Now, two lines are parallel to each other only if they have the same slope.
So, the required line also have undefined slope, so it implies that the line is a vertical line of the form
Also it is given that is passes through the point
Substitute
Thus, the equation of required line is,
Conclusion:
The equation of line that passes through the point

Answer to Problem 78E
Explanation of Solution
Concept Used:
Slope intercept form of equation of line is
Point slope form of equation of line is
Consider,
The lines of the form
Now, two lines are perpendicular to each other only if their slopes are negative reciprocals of each other.
So, the slope of the required line is
This implies that the line is a horizontal line of the form
Also it is given that is passes through the point
Substitute
Thus, the equation of required line is,
Conclusion:
The equation of line that passes through the point
