Linear Inequalities: Estimations
Multiple linear inequalities with two unknowns
The two lines given by the equations #-42\cdot x+42\cdot y-336=0# and #-38\cdot x-6\cdot y-872=0# divide the plane into four areas, indicated in the figure below as I, II, III and IV.
Which area is the solution of the following inequalities?
\[-42\cdot x+42\cdot y-336\gt0, \quad -38\cdot x-6\cdot y-872\lt0 \]
