Answer:

No, it is not a linear equation

Step-by-step explanation:

This equation contains the term x², meaning that it is a quadratic function (parabola)

So, it is not a linear equation.

If it were a linear equation, x would not be squared, and the equation would have been in y = mx + b form.

The answer is no, it is not a linear equation.

<h2>Greetings!</h2>

Answer:

2 feet per year

Step-by-step explanation:

First, we need to find the amount it grew:

13 - 3 = 10

So between 2005 and 2010 it grew 10 feet.

Now to find the yearly growth we need to divide the distance by time:

10 ÷ 5 = 2

So it grew 2 feet per year.
