Javier makes a double bar graph that shows the number of cats and dogs owned by members of his class. If Javier himself owns one dog and two cats, how will the heights of the bars compare?

To compare the heights of the bars in the double bar graph, we need to determine how the number of cats and dogs owned by Javier's classmates are represented.

In the double bar graph, each bar represents a specific category or group. In this case, one bar represents the number of cats owned by the classmates, and the other bar represents the number of dogs owned.

Since Javier himself owns one dog and two cats, we can conclude that the height of the bar representing dogs will be 1 unit, while the height of the bar representing cats will be 2 units.

Therefore, the height of the bar representing the number of cats (2 units) will be taller than the height of the bar representing the number of dogs (1 unit).
