Coordinate Grid Setup and Scaling

Mrs. Lusy's math lesson focuses on drawing the coordinate plane and plotting points. The lesson covers setting up a coordinate grid, labeling axes, and plotting ordered pairs. It also explores adjusting number scales for axes, with examples of both increased and decreased scales. The lesson provides practical exercises and tips for effectively plotting points on a coordinate grid.

What is the first step in setting up a coordinate grid?

• Calculate the scale

• Label the quadrants

• Draw the axes and label them

• Plot the points

Why is it important to label the ordered pairs on a coordinate grid?

• To avoid using rulers

• To ensure the grid is balanced

• To identify the points easily

• To make the grid look neat

What should you do if the y-coordinates exceed the current scale of the grid?

• Label them with letters

• Plot them on a separate grid

• Adjust the scale of the y-axis

• Ignore the points

When using an increased number scale, what is a potential benefit?

• It simplifies the labeling process

• It allows more points to fit

• It reduces the number of lines

• It makes the grid smaller

How can you fit points with decimal x-coordinates on a grid?

• Round the numbers

• Ignore the decimals

• Decrease the number scale

• Use a larger grid

What is the smallest x-coordinate in the given data set?

• -14

• -10

• 0

• 4

What scale should be used if the x-coordinates range from -14 to 14?

• Scale of 5

• Scale of 2

• Scale of 10

• Scale of 1

What is the largest y-coordinate in the given data set?

• 5

• 4

• 10

• 3.5

How can you make the y-axis less crowded if the range is from -4 to 3.5?

• Use a scale of 5

• Use a scale of 1

• Use a scale of 0.5

• Use a scale of 2

What is the benefit of using a scale of 0.5 for the y-axis?

• It simplifies calculations

• It reduces the number of points

• It allows for more precise plotting

• It makes the grid larger
