less than or greater to isn't an actual inequality sign is it less than or equal to OR is it greater than or equal to

jimthompson5910 (jim_thompson5910):

this sign \(\large \le\) OR this sign \(\large \ge\)

OpenStudy (anonymous):

First one

jimthompson5910 (jim_thompson5910):

so it is \[\Large -4x - y \le -2\] right?

OpenStudy (anonymous):

yes

jimthompson5910 (jim_thompson5910):

ok thanks

jimthompson5910 (jim_thompson5910):

we have a solid line since there's a line under the inequality sign

jimthompson5910 (jim_thompson5910):

\[\Large -4x - y \le -2\] \[\Large -4(0) - 0 \le -2\] \[\Large 0 - 0 \le -2\] \[\Large 0 \le -2\] which is FALSE, so (0,0) is NOT in the shaded region

OpenStudy (anonymous):

So its B?

jimthompson5910 (jim_thompson5910):

good
