Interpreting Graphs and Tables of Variables

What is the role of the variable 'x' in an equation?

• None of the above

• Constant value

• Independent variable

• Dependent variable

What does the variable 'y' typically represent in equations discussed in the video?

• A function name

• A dependent variable

• An independent variable

• A constant value

What is the first step in converting a graph to an equation according to the lesson?

• Plot the graph

• Identify the variables

• Create a table

• Calculate the slope

What is the purpose of creating a table from a graph?

• To plot a new graph

• To determine the relationship between variables

• To calculate the area under the curve

• To identify the variables

How many points' coordinates are suggested to be taken from the graph to create a table?

• Eight to nine

• Two to three

• Four to five

• Six to seven

What does the 'x' variable represent in the example discussed?

• Number of bags

• Number of pencils

• Number of pages

• Total cost

What does the 'y' variable represent in the example used in the lesson?

• Number of pages

• Total cost

• Number of pencils

• Number of bags

By how much does the cost increase for each additional page added, as per the example?

• 10 cents

• 25 cents

• 75 cents

• 50 cents

What is the derived equation from the graph in the lesson?

• x = 50y

• y = 0.5x

• x = 0.5y

• y = 50x

What is the final step in converting a graph into an equation as discussed in the video?

• Creating a graph

• Identifying a pattern and deriving an equation

• Calculating the derivative

• None of the above
