I am having a horrible time with my math homework. Can someone try to explain this to me? (6,-9);9x-2y=3 I think I am suppose to find the slope and intercept.

(x,y) so; x=6, and y=-9.

The equation you have needs to be solved for y in order to find the slope and y-intercept.

9x -2y =3
-2y =-9x +3
y = (9/2)x - (3/2)

Your yintercept is the value for "y" when "x=0": (-3/2)

The slope of the line is whatever is sitting next to the "x"; which in this case is (9/2)

Does (x=6, y=-9) make a true statement tho: 9(6) -2(-9) = 3?
54 + 18 = 3?  False.  So your given value (6,-9) are not a solution.

The information you are given suggests that you are wanting to determine if (6,-9) is a solution to the equation (9x -2y =3).  So just plug in (x=6, y=-9) and see if it is a true statement....
