Finding the slope of a line

Question

Does anyone no how to find the slope of the line of the points being (5, -3) and (-2, 5)?

Answer 1

To find the slope of a line you need to find the change in y divided by the change in x.  In other words, (y2-y1)/(x2-x1).  

Your two y-values are -3 and 5. Therefore:

(5 - -3) = (5+3) = 8

Your two x-values are 5 and -2.  Therefore:

(-2-5) = -7

So the (change in y)/(the change in x) =

8/-7

Therefore:

m = -8/7

(Note:  m is the mathematical constant/symbol for slope)
