Answer:
We conclude that the length of LM if L(3,4) and M(1,-2) will be:

Hence, option D is correct.
Step-by-step explanation:
Given
Determining the length of LM
The length of the distance between (x₁, y₁) and (x₂, y₂) can be determined using the formula

substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)








Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:

Hence, option D is correct.
Change/original * 100
