Graph line containing the given pair of points and find the slope.
(5,1) (4,2)

slope is (Y2y1)/(x2x1)
the line will be y=mx+b
put in either of the points, and m, and solve for b. 
So the point slope form does not apply to this problem?

Your question did not ask for the equation of the line.
bobpursley showed you how to find the slope
plot the 2 given points on a graph and join them with a straight line.
