Sample practice questions
Easy
1. What are the coordinates of the origin on the Cartesian plane?
(0;0)
(1;1)
(0;1)
(1;0)
Answer: (0;0) — The origin, where the x-axis and y-axis cross, is always (0;0).
Easy
2. To plot the point (3;2), which direction do you move first, and how far?
Answer: 3 units right — The x-value (3) tells you to move 3 units right from the origin first, then 2 units up for the y-value.
Medium
3. Describe how to plot the point (−2;4).
Answer: 2 units left, 4 units up — Negative x means move left: 2 units left. Positive y means move up: 4 units up.
