Question 1038860
x+2y<=250 this is a very high number. Are you sure it's 250?
y <= 250/2-x
y <= 125-x 
Pick a couple of values for x:
x..............y <= 125-x...............Ordered Pair
-2 ............. 125-(-2) =127............. -2,123
 0 ............. 125-0 = 125 .............. 0,125
 1 ............. 125-1 = 124 .............. 1,124
Now you can graph this equation. Do the others the same way
