Use the image to answer the question. The stretch of a spring in millimeters is proportional to the weight in grams attached to the end of the spring. Find the unit rate.

Answer 1

To find the unit rate for the stretch of a spring in relation to the weight attached to it, you need two key pieces of information:

1. The amount of stretch (in millimeters) when a certain weight (in grams) is applied.
2. The corresponding weight that causes that stretch.

The unit rate is calculated by dividing the stretch (in millimeters) by the weight (in grams).

For example, if attaching 100 grams to the spring results in a stretch of 50 millimeters, the unit rate calculation would be:

\[ \text{Unit Rate} = \frac{\text{Stretch (mm)}}{\text{Weight (g)}} = \frac{50 , \text{mm}}{100 , \text{g}} = 0.5 , \text{mm/g} \]

This means the spring stretches 0.5 millimeters for every gram of weight added.

To proceed, please provide the values for stretch and weight from the image or any specific data points available.
