Perform the correct steps until you have plotted all possible visible points. (The final graph will be shown after the next equation.)

• 3 units up, 2 units right

• 6 units down

• 3 units down, 2 units right

• 2 units down, 3 units right

• 2 units up, 3 units right

• 6 units up

• 3 units up, 4 units right

• 2 units up

• 3 unit down, 4 units right

• 4 units down, 3 units right

• 3 units up, 2 units right

• 6 units down

• 3 units down, 2 units right

• 2 units down, 3 units right

• 2 units up, 3 units right

• 6 units up

Answer explanation

DON'T SKIP THIS!

Perform the correct steps until you have plotted all possible visible points. (The final graph will be shown after the next equation.)

• 9 units up

• 5 units down, 1 unit left

• 9 units down

• 5 units down, 1 unit right

• 5 units up, 1 unit left

• 1 unit up, 5 units right

Answer explanation

DON'T SKIP THIS!

You would have normally plotted 5 units up, 1 unit right, but there was no room to make a point that way. Therefore, you had to immediately go in the opposite directions of 5 down & 1 left.

Perform the correct steps until you have plotted all possible visible points. If correct, the graph of both equations should match the picture shown.
