A science class began recording the height of a plant each day. On day 10, it was 20 cm tall. On day 35, it was 57.5 cm tall. What does the slope of this scenario represent?

The slope represents the plant’s change in height per day. From day 10 to day 35, it grew 57.5 − 20 = 37.5 cm over 35 − 10 = 25 days, so the slope is 37.5 ÷ 25 = 1.5 cm per day. Therefore, choice A is correct: the plant grew 1.5 cm each day.
