a. use the slope formula:



where and are the coordinates of points P and Q.

b. Presuming you mean "what is AN equation of the line containing the segment PQ", use the point-slope form of an equation of a line:



where are the coordinates of either point P or point Q and is the slope calculated in part a.

c. Use the midpoint formulas:

and



where and are the coordinates of points P and Q. Then the midpoint is the point

d. Again, presuming you mean "AN equation": The perpendicular bisector of PQ is the line perpendicular to PQ that passes through the midpoint. The slope of a line perpendicular to a given line is the negative reciprocal of the slope of the given line. Calculate the negative reciprocal of the slope that you calculated in part a, that is calculate . Then use the point-slope form of an equation of a line to derive the desired equation:



where are the coordinates of the midpoint of segment PQ and is the negative reciprocal of the slope calculated in part a.
