Question

Mahala is standing and fishing on a dock that is 2 1/4 feet above the surface of the water in the pond. Her baited hook is 1.5 feet below the surface of the water. The surface of the water is represented by the rational number 0. Use the number line to graph the distance the dock, point D, is above the water and the hook, point H, is below the water. Make sure you label each point appropriately.

Answer 1

Answer:

The graph is shown below.

Step-by-step explanation:

Take the distance above surface of water as positive and negative for below the surface.

Given:

Distance of dock from the surface of water, $D=2\frac{1}{4}=\frac{9}{4}=2.25\textrm{ ft}$

Distance of hook from the surface of water, $H=-1.5\textrm{ ft}$

The surface of water is the reference point and hence it has a value of 0.

Now, on a number line, the values to the left of 0 mark is negative and values to the right are positive.

Therefore, H will lie on the left of 0 mark and D will lie on the right as shown below.
