1) The first one will be a (more than or equal to sign) since the line is solid, and it is referring to the area in front of the line rather than behind 3rd option
2)This will be just (more than) because it is dotted and is referring to the area above. 4th option
3)What you do is put the all the numbers into the equation (x,y) The one that will work is (-3,-4) cause -4<-(-3)-5 to -4<-2 and it stays true. 2nd Option
4) What you do for here is get the y on one side first by bringing the 5x over to the 15 and getting -3y<=-5x+15 then you divide the -3 out of both sides to have y<=5/3x-5 -5 will be your y-intercept. 3rd Option
