Question 316606: solve the system of inequalities
y greater -3x
4y+2x less than are equal -2
Im not sure how to solve or graph this Answer by texttutoring(324) (Show Source):
Simply treat the inequality as an equals sign, and graph the line y=-3x, but use a dotted line because it is just a > sign.
4y+2x < -2
Isolate for y:
4y < -2x - 2
y < -2x/4 -2/4
y < -x/2 -1/2
Treat this the same as y = -x/2 -1/2
Draw the 2 lines (the first one is dotted because it's less than, the second one is a solid line because it's less than or equal to).
Shade in the region that is above the y=-3x line and below the other line. The shared region should be a little triangle in the 4th quadrant (bottom right corner)
