Multiple Choice

Derek is plotting points on a coordinate plane. From the origin, he moves 9 units LEFT along the x-axis. Then he moves 5 units UP. What are the coordinates of the point he plots?

• (9, 5)

• (9, -5)

• (-9, 5)

• (-9, -5)

Good results or not, always remember:

• X comes first! Always start going from left to right. Left means negative, right means positive!

• Y comes second! Continue from where you stopped on the x-axis. Either go up for a positive number or down for a negative number!

• You are amazing! Let's keep practicing! 👍
