Linear equation

Step-by-step explanation:

Given

The attached

Required

Determine the type of function

We start by checking for linear function

A linear function is such that:

The above represents the slope

For any pair of coordinate points, the slope must be constant.

We have:

The slope (m) is:

Take another pair:

The slope (m) is:

The slope remains constant

Hence, it is a linear function

1/4 because there is 4 grades.
