Find the slope of the line passing through the points (4,8)(4,8)and (1,6)(1,6).Enter your answer, in simplest form, in the boxes.

You have a formatting problem here, since each point is repeated.

Let's assume that you want the slope of the line passing thru (4,8) and (1,6).
                             6-8        -2
The slope is m = -------- = ----- = 2/3
                              1-4       -3
