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?
