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) =

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)

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)
