Question

Points L, M, N are collinear such that d(L,M) = 9.5, d(M,N) = 7.8, find d(L,N) .​

Answer 1

Answer:

LN+MN=LM

LN+7.8=9.5

LN=9.5-7.8

LN=1.7 units

I hope it will helps you...........

Answer 2

Answer:

Given points are L(1,2),M(5,3),N(8,6)

Slope of LM=

5−1

3−2

=

4

1

Slope of MN=

8−5

6−3

=

3

3

=1

Thus, the slope of LM not equal to slope MN.

So, the given points are not collinear
