Question

what is the slope and equation of a line that is perpendicular to the y-axis passing through (-5,-3)?​

Answer 1

Slope is m=0

`y=-3`

Explanation:

The slope of any line that is perpendicular to the y-axis is zero.

The reason is that any line that is perpendicular to the y-axis is also parallel to the x-axis and the slope of the x-axis is zero.

The equation of any line perpendicular to the y-axis is and passes through (a,b) is y=b.

The given point is (-5,-3) hence the required equation is

`y=-3`
