Answer: I am going tot give you an example for this because I don’t like giving straight up answers ok?

Step-by-step explanation:

Lets use this conversion factor:

4 inches = 1 year

Let's find the year at 5 feet (60 inches) using the conversion factor. Set up a proportion.

4 / 60 = 1 / x

Cross multiply.

4x = 60

x = 15

At 15 years, the height is 60 inches.

We can use these as points.

x = time in years

y = height in inches

Point 1 = (1, 4)

Point 2 = (15, 60)

By looking at the points, we know that as the x values increase, so does the y values. Now the relation between the x and y values of each point is that y is 4 times as that of x. Therefore, we can establish an equation.

y = 4x

This will be the model to use to find the height in 30 years.
