A table relates two variables, such as:

• Mass and density

• Length and time

• Mass and volume

• Variables and results

A is useful for showing changes that occur in related variables.

• Bar graph

• Circle graph

• Line graph
• Table

In a line graph, the manipulated variable is generally plotted on the:

• y-axis

• vertical axis

• x-axis

• diagonal line

A graph's data points may yield a:

• Slope

• Curve

• Straight line

• All of the above

The slope of a line is defined as:

• Rise over run

• x/y

• Rate of change

• Time over distance

Plotting mass against volume yields a:

• Curve

• Ratio

• Straight line

• Variable slope
