Slope Formula mini-quiz

Find the slope of the line passing through the points (–1, 1) and (–2, –3).
slope formula:

1:	In the slope formula, on top we get:
			(1) – (–3)
			(1) – (–2)
			(1) – (–1)
			(–3) – (–1)
			(–3) – (–2)
2:	This simplifies as:
			–4
			–2
			2
			4
			something else
3:	In the slope formula, underneath we get:
			(–2) – (–3)
			(–2) – (–1)
			(–1) – (–3)
			(–1) – (–2)
			(–1) – (1)
4:	This simplifies as:
			–3
			–1
			1
			2
			something else
5:	So the slope is:
			m = 3
			m = 4
			m = 1/2
			m = 1/3
			m = 1/4
