What is the length of LM if L(3,4) and M(1,-2)? Round to the nearest tenth. A) 7.2
B) 6.0
C) 2.8
D) 6.3

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.

i’m kinda new to precal but your answer should be 21. hope i got it right.
