Question 471034
y2 - y1
-------- = slope
x2 - x1


a) (4,5) and (3,8)

8 - 5
------ {substituted into slope formula}
3 - 4



3
--- = slope {subtracted on top and bottom}
-1


slope = -3 {reduced}



b) (‐2, ‐2) and (4, ‐4)
-4 - (-2)
--------- = slope {substituted into slope formula}
4 - (-2)


-4 + 2
------- = slope {simplified on top and bottom}
4 + 2


-2
--- = slope {added on top and bottom}
6


slope = -1/3 {reduced}
