Those are not the line; they are the coordinates of two points ON the line, (x1,y1) and (x2,y2).

The slope is m = (y2 -y1)/(x2-x1)

Use either point to calculate b in the standard equation format

y = mx + b

I have a suspicion that the 10/8 you have written is supposed to be 10.8.

Did you hit the wrong key?
