Linear Inequalities: Estimations
Multiple linear inequalities with two unknowns
The two lines given by the equations #-43\cdot x+42\cdot y-319=0# and #-17\cdot x-20\cdot y-585=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?
\[-43\cdot x+42\cdot y-319\gt0, \quad -17\cdot x-20\cdot y-585\gt0 \]
