Calculate the slope of the line that contains the points (-3,2) and (5,12)

Slope = (y2 - y1)/(x2 - x1)
slope = (12 - 2)/(5 + 3)
slope = 10/8
slope = 5/4
or
slope = 1.25

To find the slope of a line from two point coordinates, we use the two coordinate points given and put into the slope line formula;

y2-y1=m(x2-x1) where m is our slope value.

So using our given coordinates we have;

12-2=m(5-(-3))
10=m(8)
m=5/4 or 1.25

Hope this helps. Any questions please just ask. Thank you.
