Whats the rate of change (1, 9.5), (2, 12), (3, 14.5), (4, 17)

To find slope between two given points:

(y2-y1)/(x2-x1)

Find the difference between the first two points

12-9.5/2-1 = 2.5/1 = 2.5

14.5-12/3-2 = 2.5/1 = 2.5

17-14.5/4-3 = 2.5/1 = 2.5

The rate of change between each point is 2.5

Step-by-step explanation:

don't report but were is the digram

step-by-step explanation:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
