Linear Inequalities: Estimations
Multiple linear inequalities with two unknowns
The two lines given by the equations #-43\cdot x+46\cdot y-247=0# and #-16\cdot x-20\cdot y-580=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?
\[-43\cdot x+46\cdot y-247\gt0, \quad -16\cdot x-20\cdot y-580\lt0 \]
