Find the slope of the line that passes through (7,2) and (9,3).

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` .
