Point Slope Form of an Equation

  • The point-slope form of a linear equation is an equation of the form y – y1 = m(x – x1), where m is the slope of the graph and the point (x1, y1) is a point that lies on the graph.

  • If you are given a point that lies on a line and the slope of the line, you can immediately write the equation in point-slope form.

  • If you are given two points that lie on a line, first find the slope using the formula for the slope, then use either point to write the equation in point-slope form.

  • You now have 3 forms of a linear equation: point-slope, slope-intercept, and standard form. You can convert from one form to the other two forms using algebraic transformations of the given equation.
