Question

1. a line of symmetry is the y - axis then the line is

is vertical and passes through the origin
is horizontal and passes through the origin
is oblique and passes through the origin
the y - axis is not a line of reflection

Explanation:

The y - axis is a vertical line. In a coordinate system, the y - axis has the equation \(x = 0\). A line of symmetry being the y - axis means it is a vertical line. Also, the y - axis passes through the origin \((0,0)\) as when \(x = 0\) and \(y=0\) (the origin), the point lies on the y - axis.

Answer:

is vertical and passes through the origin
