Can someone please help me ?
|dw:1355616202401:dw| Find the rate of change and explain how you found it ???
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.
So I wouldn't do anything with the 6 and the 30?
no not in this case because i picked the first two points you can however use the first and third points if you want
you can pick any two points you want
OHHH so like it doesnt matter?
Like would it make a difference if I used different ones
no it wouldn't, you can use the first and third or the second and third points if you wanted
you will get the same slope everytime
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.
Okay thank yous so much!!!!
