Responses

y=1
y is equal to 1

y=x
y is equal to x

x=1
x is equal to 1

x=−y

Answer 1

The line that is perpendicular to the x-axis is \(x = 1\).

The other options are either horizontal lines (like \(y = 1\)) or diagonal lines (like \(y = x\) and \(x = -y\)). The line \(x = 1\) is a vertical line, which is what is perpendicular to the horizontal x-axis.
