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

The slope point form equation of a line with a slope of 4/3 and goes through the point of (-4,6) would be y-6=4/3(X+4).
