Based on the provided linear graph, which shows the relationship between femur length (in centimeters) and expected height (in centimeters), you are likely asked to interpret specific points on the graph.

Let’s examine each option:

1. "The expected height for someone with a femur length of 50 centimeters."

   • To interpret this, locate 50 centimeters on the x-axis (femur length) and find the corresponding y-value (expected height).

2. "The femur length for someone with an expected height of 189 centimeters."

   • For this option, find 189 centimeters on the y-axis and check the corresponding x-value (femur length).

3. "The femur length for someone with an expected height of 50 centimeters."

   • This would require finding 50 centimeters on the y-axis (expected height) and finding the corresponding x-value (femur length).

4. "The expected height for someone with a femur length of 189 centimeters."

   • Check the x-axis at 189 centimeters (femur length) and find the corresponding y-value (expected height).

Using the graph, identify the matching pairs based on the options provided.

Would you like further clarification on any part of the graph? Here are some additional questions for further understanding:

1. How can you determine the slope of the line from the graph?
2. What does the slope represent in this context?
3. If you know the femur length, how can you predict the height accurately?
4. How would the expected height change if the femur length increases by a certain amount?
5. Can you find the equation of the line shown in the graph?

Tip: When interpreting points on a graph, always start by locating the value on the appropriate axis and then trace to the corresponding value on the other axis.
