where m is the slope and b is the yintercept. First find the slope m.
So the equation is
To find b substitute one of the two points into the equation. I am going to use (3, 2), thus
Thus the equation of the line in slopeintercept form is
To plot the graph you already know the yintercept, ^{1}/_{2}, so the point (0, ^{1}/_{2}) is on the graph. To find another point let y = 0 and you get
so x = 1. Thus (1, 0) is on the graph. Plot these two points in the plane and then use a ruler to draw the line.
I also plotted the original points and they do lie on the line. Penny
