 Choice D

x + 2y <12

2x + y < 10

Step-by-step explanation:

first write the equation in the form of y=mx+b example if the question is 2y=4x-2 write it as y=2x-1

B is the y intercept so place it on the y axis. example on the above equation the y intercept is -1.

and write the slop(m) s form of fraction like 2/1

at last count two up across 1 continue doing that stop at some point stop and connect the lines. and if it's inequality write it as form of Y= instead of Y<,> then follow the above steps at last if it's grater than shade the upper part if it's less than shade the lower part.

Hope this helps you ;)
