Mark recorded the growth of a plant over 8 weeks. The equation y=0.2 x+2

represents the height y, in inches, after x weeks.

Which of the following could be true? Select two answers.

A. The height of the plant after week 3 was about 2.6 inches.

B. The height of the plant after week 3 was about 0.6 inches.

C. The height of the plant after week 9 was about 3.8 inches.

D. The height of the plant after week 9 was about 1.8 inches.

A. The height of the plant after week 3 was about 2.6 inches.

C. The height of the plant after week 9 was about 3.8 inches.

Step-by-step explanation:

The equation given:

Y = 0.2x + 2

x represents the number of weeks

substituting x = 3 into the equation, we will have

y = 0.2 (3) + 2

y = 0.6 + 2

y = 2.6

This means that the height of the plant after week 3 was about 2.6 inches.

Also, substituting x = 9 into the equation will give

y = 0.2 (9) + 2

y = 1.8 + 2

y = 3.8

This means that the height of the plant after week 9 was about 3.8 inches.
