Question

The graph shows the relationship between the height of a tree and its age in years. What is the unit rate of growth for the tree? 0.25 feet per year 0.5 feet per year 2 feet per year 3 feet per year

Answer 1

the unit rate is 2ft per year i got 100% on a quiz for this

Answer 2

The unit rate is 2 feet per year

Explanation:

The graph is missing (See attachment)

To determine the unit growth;

First, we have to pick any two corresponding on the x and y axis

When x = 5; y = 10

When x = 1; y = 2

These can be represented as;

`(x_1,y_1) = (5,10)`

`(x_2,y_2) = (1,2)`

Next, is to determine the slope using;

`m = (y_2 - y_1)/(x_2 - x_1)`

Substitute values for x and y

`m = (2 - 10)/(1 - 5)`

`m = (-8)/(-4)`

`m = 2`

Hence, the unit rate is 2 feet per year
