Cramer’s Rule: Systems of Equations

This program for TI-83 Plus and TI-84 Plus calculators solves systems of equations using Cramer’s Rule. Enter the coefficients of two equations in standard form and the program does one of the following: finds both equations in slope-intercept form and their intersection; finds that the lines are parallel and shows their slopes, and their y-intercepts; or finds that the lines are coinciding and show their equations in slope-intercept form.
