Let y=2x−5.

The following lists the values of y corresponding to different values of x.

When x=1, then y=2(1)−5=−3

When x=4 then y=2(4)−5=−3

The points A(1,−3) and B(4,3) are plotted on the graph paper on a suitable scale. A line is drawn passing through these points to obtain the graphs of the given polynomial

It crosses X-axis at point (2.5,0)
