Plotting Points on a Coordinate Grid

The video tutorial explains how to use a coordinate grid to locate objects in space. It introduces the x-axis and y-axis, which intersect at the origin, and describes how each point on the grid can be identified by an ordered pair of numbers called coordinates. The tutorial provides step-by-step instructions on how to plot points using these coordinates, with several examples to illustrate the process. It emphasizes the similarity between plotting points on a grid and finding locations on a map.

What is the point called where the x-axis and y-axis intersect?

• Center

• Origin

• Vertex

• Intersection

In an ordered pair, which number is written first?

• The sum of coordinates

• The difference of coordinates

• The y-coordinate

• The x-coordinate

How do you determine how far to move on the x-axis when plotting a point?

• By the first number in the ordered pair

• By the second number in the ordered pair

• By the sum of the ordered pair

• By the difference of the ordered pair

What is the ordered pair for point L?

• 2,8

• 5,9

• 4,4

• 7,3

Which point is located at the coordinates 5,9?

• Point L

• Point M

• Point N

• Point O

What is the ordered pair for point O?

• 4,4

• 9,0

• 2,8

• 3,10

Which point is located at the coordinates 9,0?

• Point M

• Point N

• Point P

• Point Q
