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 in 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.

Therefore, the equation of the line is y= - 3. To draw the graph of this equation , plot the points (1,-3), (2,-3) and (3, -3) and join them. This is the required graph.
