Question

Which of the following is an equation of a line that passes through the point (3,2) and is parallel to the y-axis?

Answer 1

check the picture below.

Answer 2

D. X=3

Explanation:

The line to be parallel to the Y-axis, it has to be a line placed in the X-axis.

This is because if you have X as a point, you will never cross the Y-axis.

But they give you the point P(3,2) this means X=3, and Y=2

So, the line you need to draw, to be parallel to Y-axis, and passes through point P(3,2) is X=3.
