Question

A plant grows at a linear rate. After six weeks, the plant is 60 cm tall. Write an equation that represents the relationship between the height (y) of the plant and the number of weeks of growth (x).

A) y = 10x
B) y = 6x
C) y = 60x
D) y = 10 + 6x

Answer 1

The equation that represents the relationship between the height (y) of the plant and the number of weeks of growth (x) is y = 10x.

Step-by-step explanation:

The equation that represents the relationship between the height (y) of the plant and the number of weeks of growth (x) is y = 10x.

This is because the plant grows at a linear rate, meaning that the change in height is constant for each week of growth.

Since the plant is 60 cm tall after six weeks, we can substitute the values into the equation to check if it holds true: 60 = 10(6), which simplifies to 60 = 60. Therefore, the equation is correct and represents the given information.
