find the slope and y intercept of line. (11.6,15.8) and (10/8,12.8)

Math 
drwls,
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)/(x2x1)
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?
