Plotting Points

Mr. Added introduces the concept of ordered pairs and how they are used to plot points on a coordinate grid, using a map of Ohio as an example. He explains how to find the coordinates of cities like Columbus, Cincinnati, and Cleveland. The video then demonstrates plotting points on a coordinate grid using ordered pairs, labeling each point. Mr. Added concludes by expressing his enthusiasm for plotting points and encourages students to enjoy the process.

What is an ordered pair used for in geometry?

• To determine the angle between two lines

• To measure the length of a line

• To calculate the area of a shape

• To describe a location on a coordinate grid

How do you find the location of a point using an ordered pair?

• By measuring the distance from the origin

• By using the X and Y coordinates to find the intersection

• By calculating the midpoint of the line

• By determining the slope of the line

What are the coordinates for Columbus, OH on the Ohio map?

• B5

• A2

• F7

• D3

Which city is located at the coordinates F7 on the Ohio map?

• Cincinnati, OH

• Cleveland, OH

• Toledo, OH

• Columbus, OH

What is the first step in plotting the ordered pair (3, 5) on a coordinate grid?

• Move up 5 units on the Y axis

• Move over 3 units on the X axis

• Draw a line from the origin

• Label the point as A

If the ordered pair is (0, 2), where do you plot the point?

• 2 units up on the Y axis

• At the intersection of X=2 and Y=0

• At the origin

• 2 units over on the X axis

What is the label for the point at the ordered pair (7, 0)?

• Point A

• Point B

• Point C

• Point D
