|y|0|x|2. Draw the four straight lines y=±3x±6. The periphery of the so formed rhombus, with vertices at (±2,0)and(0,±6), is the graph for the given equation.

Explanation:

|y|0|3x|6|x|2.

The given equation is the compounded equation for the quadruplet ±y=6±3xy=±3x±6.

These lines, in pairs, meet at (±2,0)and(0,±6) and form a rhombus. of side 40..

The rhombus reaches the limits x=±2, from within.

Only the coordinates (x, y) of points on this rhombus are governed by the given equation. The rhombus is the graph.
