Let's recall the Distributive Property that we used in this exercise. In the book we are told that simplifying expressions such as the one form this exercise will help us prepare for the next chapter. The next chapter is about the point-slope form.
A linear equation with slope m through the point (x_1,y_1) is written in the point-slope form if it has the following form. y-y_1 = m(x-x_1) In this equation, (x_1,y_1) represents a specific point on the line, and (x,y) represents any point also on the line. Graphically, this means that the line passes through the point (x_1,y_1).
x_2= x, y_2= y
LHS * (x-x_1)=RHS* (x-x_1)
