Graphing a system of three linear inequalities using slope intercept form ex 18

The video tutorial demonstrates how to graph a system of three linear inequalities. It begins with converting the inequalities into slope-intercept form, followed by graphing each inequality on a coordinate plane. The tutorial emphasizes identifying the y-intercept and slope for accurate graphing. It also covers testing solutions using a test point to determine the correct shading for the feasible region. The tutorial concludes with identifying the feasible region formed by the inequalities.
