x−5=0 is parallel to y−axis. Find the value of x co-ordinate where it crosses x−axis.
Given, x−5=0=>x=5
In the linear equation x=5, there is no term for y. This means, that y can take any value. Points lying on the line x=5 can be (5,0),(5,4) or (5,−7). Plotting these points on the graph paper and joining them, we get the graph for x=5.
Thus, given line cut the x−axis at 5.
