Question

which equation represents a line which is perpendicular to x = 0? answer y = -1 x = 1/4y x = -4y x = 6

Explanation:

Step1: Identify the type of line $x = 0$

The equation $x=0$ represents the $y -$axis, which is a vertical line.

Step2: Recall the property of perpendicular lines

A line perpendicular to a vertical line is a horizontal line. The equation of a horizontal line is of the form $y = k$, where $k$ is a constant.

Step3: Check the options

Among the given options, the equation $y=-1$ is of the form $y = k$ (where $k = - 1$), representing a horizontal line.

Answer:

$y=-1$
