Given data:

Plot the points
on the number line.
Let us plot the first point
.
1 unit is completed. So count after 1 (indicated) in the number line.
point after 1 is

point after
is

point after
is

point after
is
.

2 unit is completed. So count after 2 (indicated) in the number line.
point after 2 is

point after
is

point after
is

So, move 3 points after 2 in the number line is
.
The number line is attached below.
