Linear Inequalities: Estimations
Multiple linear inequalities with two unknowns
The two lines given by the equations #-45\cdot x+45\cdot y-225=0# and #-29\cdot x-7\cdot y-697=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?
\[-45\cdot x+45\cdot y-225\lt0, \quad -29\cdot x-7\cdot y-697\lt0 \]
