Points points ! pls ! simple the function g is defined by g(x)=9k−4, where k is a constant. find k, if the graph of g passes through the point (7,−2).

Graph of   g(x)=9k−4   passes thru  (7, -2).  Find k.

                   -2 =9k - 4, or 2 = 9k, or k = 2/9

However, I notice that your g(x)=9k−4 does not have "x" in the right side.  That would mean that g(x) is a constant equal to -2,

Please go back and check whether or not your   g(x)=9k−4   was copied down correctly.  Is it possible that  you meant   g(x)=9kx−4??
