Choosing the Correct Scale for Graphing

The video tutorial covers the concept of coordinate planes, focusing on the one by one coordinate plane where X and Y values are counted by one. It explains how to adjust scales to fit larger values, such as counting by twos on the X-axis to accommodate larger numbers. The tutorial also discusses determining appropriate scales for both axes and demonstrates practical applications of these scales in plotting points. Finally, it provides examples and instructions for a group activity to reinforce the concepts learned.

What is a one by one coordinate plane?

• A plane that can fit any number.

• A plane where each unit is counted by one.

• A plane where each unit is counted by two.

• A plane where only positive numbers are used.

Why can't the number 185 fit on a standard one by one coordinate plane?

• Because it is a fraction.

• Because it is a decimal number.

• Because the plane only has room for 10 spots on each axis.

• Because it is a negative number.

How can you adjust the x-axis to fit larger numbers like 185?

• Count by fives.

• Count by threes.

• Count by twos.

• Count by ones.

What is the range of x-coordinates discussed in the video?

• -10 to 10

• -4 to 9

• 0 to 5

• -5 to 5

Is it possible to count the x-coordinates by ones in the given range?

• Yes, because the range is small.

• No, because the range is too large.

• No, because the range is positive.

• Yes, because the range is negative.

What scale is used for the y-axis when plotting the point (-4, 20)?

• Counting by fives

• Counting by twos

• Counting by ones

• Counting by tens

What is the importance of choosing the correct scale for the y-axis?

• To make the graph easier to draw.

• To ensure all points fit within the graph.

• To make the graph look colorful.

• To avoid using negative numbers.

In the advanced example, what is the smallest unit used for the x-axis?

• 2

• 0.5

• 0.1

• 1

Why is it important to check the scale before plotting all points?

• To avoid redoing the graph if a better scale is found.

• To make the graph look complex.

• To ensure the graph is colorful.

• To use the largest possible numbers.

What should you do if you choose the wrong scale for plotting?

• Ignore it and continue.

• Erase and start over with the correct scale.

• Use a different color.

• Plot only the positive points.
