m= slope
substitue into the equation m= y2-y1/x2-x1
a) (x1,y1) (x2,y2) (1,2) (3,5)
=5-2/3-1
=3/2
Therefore the slope of the pairs is 3/2

b) (0,0) (4,6)
m= y2-y1/x2-x1
=6-0/4-0
=6/4
simplify to 3/2
Therefore the slope of the pairs is 3/2

c) (-1,2)(4,5)
m= y2-y1/x2-x1
=5-2/4-2
=3/2
Therefor the slope of the pairs is 3/2
