add 17 to both sides 17+11
OpenStudy (agent0smith):
You want to get y by itself
Start by adding 17 to both sides
OpenStudy (anonymous):
you should get 28 then divide -7y by both sides
OpenStudy (anonymous):
you should have y>-4
OpenStudy (agent0smith):
^that isn't correct, you forgot a key step

what?
OpenStudy (agent0smith):
well this part isn't correct either "then divide -7y by both sides" you don't divide by -7y...
and when you you divide by a negative, the direction of the inequality sign changes.
OpenStudy (anonymous):
oh ya forgot that part, so its y<-4
OpenStudy (anonymous):
lol thanks guys :)
OpenStudy (anonymous):
and the graph should be a dotted line too with -4 being the y intercept :)

open circle because it's a < sign (not also equals to) and y has to be less than -4, so arrow going left
