A scientist conducting an experiment creates a table to record the growth of two plants. The scientist uses the equations below to represent the growth of the plants, where w is the number of weeks of plant growth and h is the height of the plant in inches. Plant 1: 1.75 + one-half w = h
Plant 2: 1.75 + three-fourths w = h

Which describes the difference in the heights of the two plants in week 5?
Plant 1 is 1.25 inches taller than Plant 2.
Plant 2 is 1.25 inches taller than Plant 1.
Plant 1 is 1.75 inches taller than Plant 2.
Each plant is 1.75 inches tall.
