The double number line below shows the approximate number of pounds in a certain number Kilogramss 5 Pounds Based on the number line, about how many pounds are there in 4.5 klograms? 1. 8

2. 9

3. 10

4. 11

2. 9

Step-by-step explanation:

If you look at the chart, for 1.5 kilograms, there are 3 pounds, for 2.5 kilograms, there are 5 pounds, and for 3.5 kilograms there are 7 pounds. If you continue the pattern, you will have 4.5 kilograms equal to 9 pounds.

Also, if you look at the chart, the spot where 4.5 would be is where 9 is, if you want to check your work.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
