Dr. Eaton covers the Point Slope Form of an Equation by first manipulating this new form into other more familiar equations before covering the representation of slope and a test point. This lesson ends with additional examples.
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
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.
