Question

Kiran and Clare like to race each other home from school. They run at the same speed, but Kiran's house is slightly closer to school than Clare's house. On a graph, their distance from their homes in meters is a function of the time from when they begin the race in seconds.

As you read the graphs left to right, would the lines go up or down?
What is different about the lines representing Kiran's run and Clare's run?
What is the same about the lines representing Kiran's run and Clare's run?

Answer 1

The lines go up as we read the graph from left to right. Kiran's line starts at a slightly lower point than Clare's line. Both lines have a positive slope, indicating the distance from home is increasing at a constant rate.

Step-by-step explanation:

The lines on the graph representing Kiran's and Clare's runs would go up as we read the graph from left to right. This is because the graph shows their distance from home increasing as time goes on.

An important difference between the lines representing Kiran's and Clare's runs is that Kiran's line starts at a slightly lower point on the y-axis compared to Clare's line. This indicates that Kiran's house is slightly closer to school.

The same thing about the lines representing Kiran's and Clare's runs is that they both have a positive slope. This means that their distance from home is increasing at a constant rate as time goes on.

Answer 2

1. Down.

2. Clare's line would be higher because she begun further away from her house.

3. The lines would have the same slope since they are going the same speed.
