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.
