|dw:1355616202401:dw| Find the rate of change and explain how you found it ???

4. jim_thompson5910

pick any two points, say (2,10) and (4,20) then find the slope m = (y2-y1)/(x2-x1) m = (20-10)/(4-2) m = 10/2 m = 5 Since the slope is 5, the rate of change is 5. If there are units (like miles and hours), don't forget these.

5. veganbee

So I wouldn't do anything with the 6 and the 30?

6. jim_thompson5910

no not in this case because i picked the first two points you can however use the first and third points if you want

7. jim_thompson5910

you can pick any two points you want

8. veganbee

OHHH so like it doesnt matter?

9. veganbee

Like would it make a difference if I used different ones

10. jim_thompson5910

no it wouldn't, you can use the first and third or the second and third points if you wanted

11. jim_thompson5910

you will get the same slope everytime

12. CheetahBooks1

NOPE! It wouldn't! It's best to try 3 or more points just to make sure that the rate of change is constant within all points.
