Because the factor would divide it into two
The rate of change of the linear equation is 
Explanation:
The given two coordinates are
and 
To determine the rate of change, let us use the formula,

Substituting the coordinates in the equation, we get,

Simplifying, we have,

Dividing, we get,

Thus, the rate of change of the linear equation is
