Answer 2

Rate of change = slope.

Answer 3

idk how to do the first part. :S

Answer 4

so using the slope formula the second part would be ((4.9)+(2.9))/(6.1-2.2) correct?

Answer 5

Why + 2.9?

Answer 6

sorry -2.9
my bad that worked

Answer 7

Yes, now it's right.

Answer 8

ok i guess thats what was making the problem wrong thanks

Answer 9

and the first one is (0-2.9)/(8-2.2)

Answer 10

@NickR u r right there first one is done this way

Answer 11

Why man? @Nick_Black

Answer 12

well u draw a straight line from points 8-2.2 than take the slope

Answer 13

Don't you think the slope will be same then? D:

Answer 14

it says average rate of change so drawing straight line gives u average

Answer 15

Ohh.

Answer 16

tht does the slope means saif
u should pay attention in sir Arif classes :P

Answer 17

u should have payed attention

Answer 18
