Linear Inequalities: Estimations
Multiple linear inequalities with two unknowns
The two lines given by the equations #-43\cdot x+35\cdot y-445=0# and #-36\cdot x-40\cdot y-460=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?
\[-43\cdot x+35\cdot y-445\gt0, \quad -36\cdot x-40\cdot y-460\gt0 \]
Which area is the solution of the following inequalities?
