Absolute value of the given number is the magnitude of the number and hence it is always positive. On a number line, absolute value of the given number is the distance of that number exactly from ‘0’ and absolute value is also always a positive number since distance always is always a positive number. Graphing absolute value includes plotting the ‘x’ and ‘y’ values on the coordinate axis to trace the graph accordingly. The graph is drawn by joining the plotted points.

Example 1: Graph the equation, y = |x|.

in order to graph the given equation, first we need to get the coordinate points.

So pick random ‘x’ value, find their ‘y’ values and plot the below points.

If x= 0, then y= |0|= 0. So the point (x, y) = (0, 0).

If x= 1, then y= |1| = 1==>(x, y) = (1, 1)

If x= -1, then y= |-1|= 1==>(x, y) = (-1, 1)   
                                               
If x= 2, then y= |2|= 2==>(x, y) = (2, 2)

If x= -2, then y= |-2|= 2==>(x, y) = (-2, 2)

Example 2: Graph the equation, y = |x- 1|.


So pick random ‘x’ value, find their ‘y’ values and plot the below points.

If x= 0, then y= |-1|= 1. So the point (x, y) = (0, 1)

If x= 1, then y= |0| = 0==>(x, y)= (1, 0)

If x= -1, then y= |-2|= 2==>(x, y)= (-1, 2)   
                                               
If x= 2, then y= |1|= 1==>(x, y)= (2, 1)

If x= -2, then y= |-3|= 3==>(x, y)= (-2, 3)
