1. Using graph paper, draw a 4-inch line from the origin parallel to the positive x-axis.

2. Draw a 3-inch vertical line from the

origin parallel to the positive y-axis.

3. Complete the rectangle with the hor.

sides 4 inches long and the ver sides 3 inches long.

4.Draw a diagonal from the origin to the upper right hand corner of the rectangle. This is the resultant.

5. Measure the length of the resultant;

it should be approximately 5 inches.
