The graph below shows a line segment PQ. Graph of line PQ going through ordered pairs negative2 comma 1 and 4 comma 4 What is the slope of the line segment PQ?

P = (-2,1) = (xp, yp) →xp=-2, yp=1

Q = (4,4) = (xq, yq) = xq=4, yq=4

Slope of the line segment PQ: m=?

m = (yq-yp) / (xq-xp)

m = (4-1) / [4 - (-2) ]

m=3 / (4+2)

m=3 / 6

m=1/2

Answer: The slope of the line segment PQ is 1/2
