The slope of the line is #11#.

Explanation:

Slope is the change in y over the change in x.

#(Deltay)/(Deltax)# OR #(y_2-y_1)/(x_2-x_1)# where the x and y values correspond with the coordinates.

Since (7,9) is the second coordinate, we use that as #x_2# and #y_2# and the other as #x_1# and #y_1# although both can be used interchangeably, as long as they are in the correct pairs.

#(9-(-2))/(7-7)#

#slope=11/1#

The slope of the line is #11#.
