Linear Inequalities: Estimations
Multiple linear inequalities with two unknowns
The two lines given by the equations #-38\cdot x+43\cdot y-391=0# and #-25\cdot x-5\cdot y-625=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?
\[-38\cdot x+43\cdot y-391\lt0, \quad -25\cdot x-5\cdot y-625\gt0 \]
