Step 1: Put x = 0 into the equation which becomes -4y = 20 so that y = -5.

So mark (0, -5) as one point on the graph.

Step 2: Put y = 0 into the equation which becomes 8x = 20 so that x = 2.5

So mark (2.5, 0) as another point on the graph.

Step 3: Join the two point and extend the line in both directions.

Step 4: Hand in your work!
