Graph:

#y=3absx#

Since #absa=+-a#, there are two equations; one in which #x# is positive, and one in which #x# is negative.

Positive X

#y=3x#

Determine two points.

#x=0,##y=0#

#x=2,##y=6#

Points: #(0,0)# and #(2,6)#

Plot the points and draw a straight line through them.

Negative X

#y=-3x#

Determine two points.

#x=0,##y=0#

#x=-2,##y=6#

Points: #(0,0)# and #(-2,6)#

Plot the points and draw a straight line through them.
