Question

find the distance formula between L(5,-8), M (-7,-3)​

Answer 1

Hello !!

For you answer this question, you only need make use of this method below. See the resolution.

dLM = √[(xM - xL)^2 + (yM - yL)^2]

dLM = √[(-7 - 5)^2 + (-3 - (-8))^2]

dLM = √[(-12)^2 + (-3 + 8))^2]

dLM = √[(-12)^2 + (5))^2]

dLM = √[144+ 25]

dLM = √169

dLM = √169 = √(13 × 13) = 13 uc.

Final result : 13 uc.

I hope I have collaborated !

Answer 2

Step-by-step explanation:

LM = √ {(-7)-(5)}2 + {(-3)-(-8)}2

LM = √ (-7-5)2+ (-3+8)2

LM = √(-12)2+ (5)2

LM = √ 144 + 25

LM = √169

LM = 13
