I.Find the slope of the line containing each pair of points.
1.) (4,5),(11,9)
2.) (4,8),(1,5)
3.) (-1,-2),(7,1)
4.) (-3,6),(-3,1)
5.)(6,-3),(6,4)

Sagot :

1.(y2-y1)/(x2-x1)
=(9-5)/(11-4)
=4/7

2.(y2-y1)/(x2-x1)
=(5-8)/(1-4)
=-3/-3
=1

3.(y2-y1)/(x2-x)
=(1+2)/(7+1)
=3/8

4.(y2-y1)/(x2-x1)
=(1-6)(-3+3)
=-5/0 (no slope)

5.(y2-y1)/(x2-x1)
=(4+3)/(6-6)
=7/0 (no slope)
