Find the slope of the line between (1,5)and (3,9)

Volgvan

We can use the points in either order and you will still get the same slope. I usually solve in order that is given. So the first coordinates I label (x1,y1) and the second is (x2,y2).

Slope=m=(y2-y1)/(x2-x1)
m=(9-5)/(3-1)=4/2=2

Slope is 2.
