Determine the direction of its movement for the line between the points (5,0),(0,2)

• negative so the line is to down ward , value of y decreasing

• positive so the line is to upward , value of y increasing

• undefined (the line is vertical),it parallel to the Y-axis, the values of x are constant.

• zero ( the line is horizontal), it parallel to the X-axis ,the values of y are constant.
