Creating a Table of Values from Graph Points

What does the x-axis represent in the graph about the cost of pens?

• Number of pens

• Distance in kilometers

• Cost in dollars

• Time in hours

If the number of pens (n) is 3, what is the cost (C) according to the graph?

• 2 dollars

• 4 dollars

• 6 dollars

• 8 dollars

Why can't we place a dot at 1.5 pens on the cost of pens graph?

• Because the graph only allows even numbers

• Because it would not form a straight line

• Because 1.5 pens is not a whole number and doesn't make sense in real life

• Because the cost would be too high

What does the y-axis represent in the graph about the position of a car?

• Distance in kilometers

• Cost in dollars

• Number of pens

• Time in hours

If the time (T) is 3 hours, what is the distance (D) according to the car position graph?

• 0 kilometers

• 140 kilometers

• 210 kilometers

• 280 kilometers

Is it possible to have a value at 2.5 hours on the car position graph?

• Yes, because time can be a continuous value

• Yes, but only if the distance is also a whole number

• No, because 2.5 hours is not a whole number

• No, because it would not form a straight line

What does the linear relation in the car position graph represent?

• The time taken

• The cost of pens

• The speed of the car

• The number of pens

How do you calculate speed from the car position graph?

• Distance multiplied by time

• Distance divided by time

• Time divided by distance

• Time multiplied by distance

If the distance is 210 kilometers and the time is 3 hours, what is the speed?

• 70 kilometers per hour

• 140 kilometers per hour

• 280 kilometers per hour

• 210 kilometers per hour

What is the speed if the distance is 280 kilometers and the time is 4 hours?

• 70 kilometers per hour

• 90 kilometers per hour

• 60 kilometers per hour

• 80 kilometers per hour
