Determine the equation of the line described. Put answer in the slope-intercept form, if possible.
-Through $( 1,4 )$, perpendicular to $x = 5$
A) $y = 5$
B) $y = - 4$
C) $y = 4$
D) $x = 5$

Question

Quizplus · Accepted Answer

The line $x = 5$ is a vertical line. A line perpendicular to a vertical line is a horizontal line. Horizontal lines have the equation $y = k$, where $k$ is the y-coordinate through which the line passes. Since the line passes through $(1,4)$, the equation of the line is $y = 4$.
