Slope of a Line given points (-2, 1) and (2, 9)

Given Coordinates: x1 = -2  y1 = 1,  x2 = 2  y2 = 9
Slope Formula: m  =  
y2 − y1/x2 − x1

Substitute the given coordinates into the Slope Formula and Simplify:
m  =  
9 − 1/2 − (-2)
m  =  
9 − 1/2 + 2
m  =  
8/4
   (Greatest Common Factor of 8 and 4, GCF(8, 4) = 4)
m  =  2
Therefore, the Slope of a Line given points (-2, 1) and (2, 9) is equal to 2
