• Axes are only used for labeling the graph and do not affect data representation.

• Axes are optional and can be omitted in simple graphs.

How do you calculate the percentage of a part in relation to a whole?

• Multiply the part by the whole and divide by 100 to get the percentage.

• Subtract the part from the whole and multiply by 100 to get the percentage.

• Divide the part by the whole and multiply by 100 to get the percentage.

• Add the part to the whole and divide by 100 to get the percentage.

Why is it important to label axes in a graph?

• It makes the graph look more appealing.

• Labeling axes is crucial for clarity, as it informs the viewer what each axis represents and the units of measurement.

• It allows for more colors to be used in the graph.

• It is not necessary if the graph is simple.
