1. 4x+Y<2
Y>-2
there are 2 inequalities with x and y (just y in the 2nd one)
so the sol'n can be shown as a region of an x-y plot
first reorganize the first eqn:
4x+Y<2
y < -4x + 2
so it represents the region underneath the line y = -4x + 2
then for y>-2:
it the region above the horizontal line y = 2
combining the two, the soln is the trianglular region underneath y = -4x + 2 and above y = 2
2. x >= -3
it represent the region right of the vertical line x = -3 and including the line itself
