For the first question, simply draw a horizontal line that has a middle number of 0. This is our number line. Then simplify plot the points.
For example, Furyk will be -3. Because he is 3 under par and par is 0.
For the second question, just find each person's score and line them up by size.
Furyk: -3
Woods: -6
Daly: +1
Couples: +6
Rearrange them by size.
-6, -3, 1, 6
And for the last question, Furyk would have a coordinate of (-3, 0).
So, the integers and the whole number would be the answer.
