points and ﬁnd the slope. (2,3) and (— 2,— 1) The graph must pass through the two points,
(8,3) and ( 2,  1). First, plot the point (8,3).
Next, plot the point ( 2,  1). Graph the line by drawing a line through the
two points, as shown on the right. The slope ofaline containing points (X1,y1)
and (X232) is given by the following formula. rise change in y y2  3’1
