Joshua conducted an experiment where he dropped rocks of the same size into a jar of water. He measured the height of the water after every five rocks. The table shows the results of his experiment. Which linear equation best represents the data shown in the table?

Ricardo is measuring the height of a plant. The starting height of the plant was 3 centimeters. He then took measurements once a week and found an average growth of 0.5 cm per week. Which linear equation can be used to find the plant’s height in centimeters, h, after w weeks?
