"(-1.2)" and "(5.7)" are two points on a number line -- not two points in an xy plane. Assuming the number line is horizontal, the slope of the line between the two points is 0.

Use commas instead of periods to show the coordinates of points in two dimensions: (-1,2) and (5,7)

If you meant to say the points (-1, 2) and (5, 7), then you can use the slope formula as shown below.

m = slope
m = (change in y)/(change in x)
m = (y2 - y1)/(x2 - x1)
m = (7-2)/(5 - (-1))
m = (7-2)/(5 + 1)
m = 5/6
