2.	Where do we have x < 0 and y < 0? In Quadrant III.
4.	(a) (10, 0)
	(b) (2, 6) by symmetry
	(c) (–4, 4) since slope of must be 3 (over 2, up 6) in order to match
6.	(a)
	(b) (1, 6)
	(c) since we can use the slope formula on points B and M (where M = answer to part (b))
	(d) by distance formula (using points B and M)
	(e) by opposite reciprocal of part (a)
	(f) since slope of is also
	(g) by opposite reciprocal of part (a)
10.	(a)
	(b) 2
	(c) The lines are (since slopes are opposite reciprocals).
