sry we are not here to do all of your work, and rules regulate 1 question per submission, lists of questions will most likly be ignored as we are here to help not complete the assignments for you.
for #'s 3,5,7,9 I do not know what your asking? please specify. if it is a coordinate at the end or are they both values for x or for y. or if your trying to see if that point satifies the equation then simply substitute the x and y for their values. i.e. #3 is not true because 3 is not >4
FOR #'s 11-15:
1) "less than or equal to" or "greater than or equal to" both have a solid line
"<" or ">" have a dotted line
2) Put the equation into slope-intercept form
3) Identify the slope and y-intercept
4) Graph the line like a normal equation with the correct line as described above.
5) Find and shade in correct direction according to what Y is. i.e. Y>X means shade up. Y
i.e. #11 
slope is 1 y-intercept is 4 the two points are (0,4)(1,5) line is dotted, area is shaded downward below line.
