Find the equation of the line that is perpendicular to the l

Find the equation of the line that is perpendicular to the line y = 5 and passes through the point (13, -9).

Find the equation of the line that is parallel to the line y = -1 and passes through the point (14, 8).

Find the equation of the line that is perpendicular to the line y = 5 and passes through the point (13, -9).

Solution:
The equation perpendicular to y=5 is of the form

x = a ... (1)

This passes through (13,-9)
So, 13 = a
Substitute this in (1),

x= 13 (Answer)

Find the equation of the line that is parallel to the line y = -1 and passes through the point (14, 8).

Solution:
The equation perpendicular to y=-1 is of the form

x = a ... (1)

This passes through (14,8)
So, 14 = a
Substitute this in (1),

x= 14 (Answer)
