Graph the system of inequalities and solve.
Y > 2x - 4
y < 2x + 1
Simply graph each inequality separately on the same set of axes. The area where the shadings overlap is the solution to the system of inequalities.
y >= 2x - 4
Let's write y = 2x - 4,
when y =0, x = 4/2 = 2 one point on graph (2,0)
The solution shows all mathamatical steps and start explaining right from the basics. You can do similar problems yourself after going through this solution. The graph is provided in an attached .jpg file.
