Question

Find the slope of the line that goes through the points (11,-3) and (9,-12).

Answer 1

Answer:

Since slope of line passing through two points (x

1

,y

1

) and (x

2

,y

2

) is m=

x

2

−x

1

y

2

−y

1

We now find the slope of the line passing through the points (−1,1) and (2,2) as shown below:

m=

2−(−1)

2−1

=

2+1

=

3

1

Therefore, the slope of the line is 1/3
