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
𝑥-axis and the number of action figures on the 𝑦-axis, we can go vertically
upwards from one until we hit our straight line and then horizontally across to the
𝑦-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.
