which one do would you choose for starters ... and why

amistre64 · Answer

since they all have the same basic form ... the only thing that differs between them is the inequality signs.

A and D would narrow it down

amistre64 · Answer

so, you think A or D is correct?

anonymous · Answer

no i'm saying A and D are out

the only other thing to do would to be test an obvious point

well first of the inequality signs and

amistre64 · Answer

lets test B, with the point 0,0 since it is clearly on one side of the boundary line

y <= 3x – 1 
0        0
-----------
0 <=  -1  , is this a true statement ?

anonymous · Answer

zero is not less than -1 so no that's incorrect

amistre64 · Answer

the B is incorrect as well .. id go with C then
