Lesson Planet
Make the connection between the intersection of two functions and a system of equations. The class watches an informative algebra video on finding the point of intersection of two linear functions. The presenter shows the steps to prove they are the same steps of finding the solution of a linear system with both equations written in slope-intercept form. Both functions contain fractional coefficients, allowing the procedure to include clearing the fractions.
