Question 236663
Slope of a line passing through two points (x1, y1) and (x2, y2) is given by

Slope m = (y2-y1)/(x2-x1)

Here, x1 = 1/2 y1 = 3/4
      x2 = 3/5 y2 = 5/4

plugging in these values for x1, y1, x2 and y2

m = (5/4-3/4) / (3/5 - 1/2)
  = 2/4 / 1/10
  = 2 * 10/4*1
  = 5

Hence the slope of line pass through said points is 5
