No, the points (4, 330) and (6, 480) would not indicate a rate of change of 80 km per hour. To calculate the rate of change, you need to find the change in distance divided by the change in time.
If the rate of change is 80 km per hour, it means that for every hour that passes, the distance increases by 80 km.
So, let's find the correct points:
If 1 hour corresponds to 80 km, then in 4 hours, the distance would be 4 times 80 km = 320 km.
If 1 hour corresponds to 80 km, then in 5 hours, the distance would be 5 times 80 km = 400 km.
Therefore, the correct points would be (4, 320) and (5, 400), indicating a rate of change of 80 km per hour.
Which two point on a linear graph showing time and distance would indicate a rate of change of 80 km per hour? Would it be
4, 330 and 6,480?
