Question

Which graph represents the relationship between variables?

Answer 1

LINE GRAPHS

• line graphs show a relationship between two variables: one measured on the horizontal axis and the other measured on the vertical axis.

• show a relationship between two variables: one measured on the horizontal axis and the other measured on the vertical axis.Sometimes it’s useful to show more than one set of data on the same axes. The data in the table, below, is displayed in Figure 1, which shows the relationship between two variables: length and median weight for American baby boys and girls during the first three years of life. (The median means that half of all babies weigh more than this and half weigh less.) The line graph measures length in inches on the horizontal axis and weight in pounds on the vertical axis.
