Question

Draw the graph of the equation represented by a straight line which is parallel to the X-axis and at a distance 3 units below it.

Answer 1

Any straight line parallel to X-axis and below the x axis is in the negative direction of y-axis is given by y = - k, where k is the distance of the line from the x-axis.
Here, k = 3
So, equation of the line will be y=-3.
