Can someone help me please? I have 4 equations that need to be matched up to different graphs. I need to know how to work the equations so I can match them to the graphs.
6y>15-3x
5x-3<15
3x>=2y -x
y+x<=-3
If you can show me how to work htese i can then match them to the graph. Thank you so much!!!!!!

Sorry, we don't do graphs
I don't know what you mean by "matched up" to different graphs.
to graph an inequality, change your equation to the form y > mx + b
or y < mx + b, whichever way it turns out
for the first one it would be the region above the line y = mx + b
for the second case it would be the region below
y = mx + b
If you have ≥ or ≤ , then the line itself would be included.
first one:
6y > -3x + 15
y > -(1/2)x + 5/2
draw a dotted line for y = (-1/2)x + 5/2, then shade in the region above that dotted line.
Do the others the same way.
Are you missing a y term in the second equation?
