You can put this solution on YOUR website! PUT THE EQUATION IN THE LINE FORM THUS
4X+Y>=4
Y>=-4X+4 THIS LINE PASSES THROUGH THE Y INTERCEPT (0,4) WITH A SLOPE OF -4
THE X INTERCEPT CAN BE FOUND BY SETTING Y=-0 THUS
0>=-4X+4
-4>=-4X
X=>-4/-4
X=>1 OR THE OTHER POINT IS (1,0)
NOW DRAW A LINE THROUGH THESE TWO POINTS (1,0)&(0,4) AND SHADE THE AREA BELOW THIS LINE TO ELIMINATE ALL VALUES OF X & Y THAT DO NOT SATISFY THIS EQUATIION.
