Plotting Points and Ratios in Graphs

This video tutorial teaches how to solve ratio problems using a fruit punch example. It covers the use of ratio tables and graphing on a coordinate plane. The lesson begins with an introduction to the fruit punch ratio, followed by a detailed explanation of using ratio tables to solve the problem. It then reviews graphing on a coordinate plane, including plotting points and understanding the x and y axes. Finally, the tutorial demonstrates how to graph the fruit punch ratio on a coordinate plane, reinforcing the concept of adding two cups of grape juice for every three cups of apple juice.

What is the ratio of grape juice to apple juice in the fruit punch recipe?

• 1:1

• 3:1

• 2:3

• 3:2

If you have 12 cups of apple juice, how many cups of grape juice are needed according to the ratio?

• 12 cups

• 6 cups

• 8 cups

• 10 cups

What is the first step in plotting a point on a coordinate plane?

• Move left on the x-axis

• Move down on the y-axis

• Move up on the y-axis

• Move right on the x-axis

What are the coordinates of the origin on a coordinate plane?

• (1,1)

• (0,0)

• (2,2)

• (0,1)

What mistake do students often make when plotting points?

• Plotting points outside the graph

• Using the wrong scale

• Mixing up the x and y coordinates

• Forgetting to label the axes

In the fruit punch example, what is the x-coordinate when you have 6 cups of apple juice?

• 4

• 2

• 8

• 6

How do you determine the next point on the graph using the ratio table?

• Add 4 cups of grape juice and 5 cups of apple juice

• Add 1 cup of grape juice and 1 cup of apple juice

• Add 2 cups of grape juice and 3 cups of apple juice

• Add 3 cups of grape juice and 2 cups of apple juice

What does the x-coordinate represent in the fruit punch graph?

• Cups of apple juice

• Cups of grape juice

• Total cups of juice

• Ratio of juices

What is the purpose of adding a zero column in the ratio table?

• To increase the number of data points

• To simplify calculations

• To represent the starting point for graphing

• To check for errors

What is the final step in representing a ratio on a coordinate plane?

• Plotting the points

• Labeling the axes

• Drawing a line through the points

• Calculating the slope
