PLEASE HELP ASAP. Which graph represents this system of inequalities? y < or equal to 2x +3 3x + y < or equal to -2
Accepted Solution
A:
y<=2x+3 y=2x+3 x=0βy=2(0)+3=0+3βy=3βPoint=(x,y)=(0,3) y=0β0=2x+3β2x+3=0β2x+3-3=0-3β2x=-3β2x/2=-3/2βx=-1.5β Point=(x,y)=(-1.5,0) y<=2x+3 is the region below the right line passes trough the points (0,3) and (-1.5,0)
3x+y<=-2 3x+y-3x<=-2-3x y<=-3x-2 y=-3x-2 x=0βy=-3(0)-2=0-2βy=-2βPoint=(x,y)=(0,-2) y=0β0=-3x-2β-3x-2=0β-3x-2+2=0+2β-3x=2β-3x/(-3)=2/(-3)βx=-2/3β x=-0.67βPoint=(x,y)=(-0.67,0) y<=-3x-2 is the region below the right line passes trough the points (0,-2) and (-0.67,0)
