Sign In
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 point-slope 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).
It is worth mentioning that the point-slope form can only be written for non-vertical lines.
x_2= x, y_2= y
LHS * (x-x_1)=RHS* (x-x_1)
