Use the graph to find out how many action figures each boy has.

As our graph has a straight line, we know that our function is linear. This means that for each extra boy, there will be the same number of extra action figures. As the number of boys is on the š„-axis and the number of action figures on the š¦-axis, we can go vertically upwards from one until we hit our straight line and then horizontally across to the š¦-axis. This tells us that when we have one boy, we have three action figures. This suggests that the answer is three. Each boy has three action figures.

We can check this by selecting some other points on the graph. Reading off the graph, we see that two boys have six action figures. We can repeat this for three, four, five, and six boys which is equal to 18 action figures.

As our graph starts at the point zero, zero, we can calculate the number of action figures that each boy has by dividing the number of action figures by the number of boys at any of these points. Six divided by two is equal to three, and 18 divided by six is also equal to three. This confirms that the correct answer is three action figures.
