Point-slope form might be less familiar and more formal-looking. It is a general form of a linear equation with a known slope and one of the points. Watch this lecture series and complete the interactive exercises.
Point-slope form - Questions
Answers
The general point-slope form , where is the slope and is a point on the line.
Why?
The point-slope form comes directly from the definition of slope. We'll use to represent slope and as one point on the graph of the equation.
Let's find the slope between and :
The incomplete equation starts with , so we need to use the point :
