Question

The point Q($-$3, $-$2) lies on a line parallel to the Y-axis. Write the equation of the line and draw its graph.

Answer 1

The x co-ordinate of a point is its distance from the Y-axis and y co-ordinate is its distance from the X-axis.

The point of intersection of the line parallel to Y-axis at a distance 3 units from it to its left and the line parallel to X-axis at a distance 2 units below it is (−3, −2).

The equation of the line parallel to Y-axis at a distance 3 units from it to its left is x = −3.
