Question

Assignment Active Finding the Difference Slide the green dot from 0 to plot the number at the correct location. Use the interactive number line to find each difference to complete the table. Add 2 by moving the green dot to the right. b a + b a-b 1 2 3 -1 2 -6 -5 -4 -3 -2 0 1 3 4 5 6 -1 -2 -3 -1 1 U -4 1 -3 V -6 -3 -9 w U= 0 That was not the correct point on the number line. V= >

Answer 1

First, we will find what the value of U is before we slide the number line to the correct position:

`\begin{gathered} U=a-b \\ a=-1 \\ b=-2 \\ U=-1-(-2) \\ U=-1+2 \\ U=+1 \end{gathered}`

So to get the number line position, we will slide the green dot from -1 position, two units to the right, and stop at +1 position.
