To deal with such problems, firstly treat the inequality as an equation with = sign. Then represent it on the graph and test the areas on its sides; which one is matches the < or > signs of the original inequality.
OpenStudy (jamaljunior):
um ok
OpenStudy (jamaljunior):
.-.
OpenStudy (3mar):
So what is the equation of the first inequality ?

yes
OpenStudy (jamaljunior):
idk how but im here now
OpenStudy (3mar):
Ok
OpenStudy (3mar):
For the first equation:\[y=-3x-2\]
and it is represented by dotted straight line because the sign < in its original inequality
OpenStudy (jamaljunior):
okay

For the second equation:
\[y=x-2\]
and it is represented by solid straight line because the sign \[\le\] in its original inequality.
OpenStudy (3mar):
Is it fine until here?
OpenStudy (jamaljunior):
yes
OpenStudy (3mar):
Are you busy?
