Since we know the coordinates of the points, we'll can use the following formula that gives the slope of the line:

`m = (y2 - y1)/(x2 - x1)` , where x1,y1,x2 and y2 are the coordinates of the points the line is passing through.

We'll identify the values of coordinates:

x1 = 7, x2 = 9

y1 = 2, y2 = 3

We'll substitute these values into the formula of the slope:

`m = (3-2)/(9-7)`

`m = 1/2`

Therefore, the slope of the line that is passing through the given points is m = `1/2` .
