Linear Inequalities: Estimations
Multiple linear inequalities with two unknowns
The two lines given by the equations #-39\cdot x+47\cdot y-317=0# and #-45\cdot x-9\cdot y-945=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?
\[-39\cdot x+47\cdot y-317\gt0, \quad -45\cdot x-9\cdot y-945\gt0 \]
