Look at the following graph of the given equation. Determine whether the equation is a function. Explain why or why not.
y= 2x+2
+ • 2.6)
+ (1.4)
(0.2)

The equation is a function

Explanation:

Given that the graph contains the coordinates , , and

We need to determine whether the equation is a function.

To determine the equation is a function, let us substitute the coordinates in the equation and check whether it satisfies the equation.

Let us substitute the coordinate in the equation

Thus, we have,

Thus, the coordinate satisfies the equation

Substituting the coordinate in the equation, we have,

Thus, the coordinate satisfies the equation

Substituting the coordinate in the equation

Thus, the coordinate satisfies the equation

Substituting the coordinate in the equation, we get,

Thus, the coordinate satisfies the equation

Hence, the coordinates , , and satisfies the equation

Thus, the equation is a function.

answer: the common difference is -0.10
