Question

Is this correct?

Answer 1

My answer:

J(6, 3) M(-3, 4)
d = √{[(6 - -3)^2] + [(3 - 4)^2]}
d = √{[9^2] + [-1^2]}
d = √{81 + 1}
d = √82
d ≈ 9.06

K(-12, 5)

Answer 3

I don't understand how you took the distance of of JM to find the coordinate K

Granted that JM = MK since M is the midpoint

mhmm

Answer 4

you are correct, but easier method is to use midpoint
\[M = (\frac{x_1 +x_2}{2}, \frac{y_1+y_2}{2})\]

Answer 5

Yeah, you could plug in the (x1, y1) values you know and the midpoint values and solve for (x2, y2)

so:

\(\Large -3 = \frac{6+ x_2}{2}\)

and

\(\Large 4 = \frac{3 + y_2}{2}\)
