The equation y = 10x + 10 is a non-proportional relationship.

Answer 2

What is the unit rate of height per day based on the graph?

(5,1) (15,3) (30,6)

Answer 3

[AI-generated answer — Bot GPT 3.5]

To find the unit rate of height per day, we can determine the change in height divided by the change in days.

From (5,1) to (15,3), the change in height is 3 - 1 = 2 units, and the change in days is 15 - 5 = 10 days. Therefore, the unit rate is 2/10 = 0.2 units per day.

From (15,3) to (30,6), the change in height is 6 - 3 = 3 units, and the change in days is 30 - 15 = 15 days. Therefore, the unit rate is 3/15 = 0.2 units per day.

Therefore, the unit rate of height per day based on the graph is 0.2 units per day.
