Use average rates of change to determine if the function in the table is Linear or Non-linear.

We have been given a table of values of a function. We are asked to determine whether the given function is linear or nonlinear.

We know that a function is linear when its rate of change (slope) is constant.

Let us find slope for each of the given points using slope formula.

Similarly, we will find the slopes using other given coordinates.  

Since the rate of change for each set of points is , so the rate of change is constant.

Therefore, the given function is linear.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
