Calculate the slope of the line between the point (-3,2) and (5,0)
Finger [1]

Answer:

The slope of the line is -1/4

Step-by-step explanation:

To find the slope, we use the formula

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


We have the points  (-3,2) and (5,0)

  = (-2)/(5+3)

  =-2/8

 = -1/4

The slope of the line is -1/4
