Question

HELP

Answer 1

M is the midpoint of JK . The coordinates of J are (6, 3) and the coordinates of M are (-3, 4), find the coordinates of K.

Answer 2

Use the mid point formula :)
\[\huge~\rm~\frac{ x_2+x_1 }{ 2},\frac{ y_2+y_1 }{ 2 } \]

Answer 3

substitute your values and solve

Answer 4

i gave you midpoint formula in previous question

Answer 5

i don't get how to go backwards though

Answer 6

By law of openstudy, article Code of Coduct, paragraph 2 , i have a right to help the user even if someone is already helping him @TheSmartOne

Answer 7

I understand who to find the midpoint but not find a point from the midpoint and end point

Answer 8

\[\bf\Large \frac{x-6}{2} = -3\]

Answer 9

Would i use the distance formula then multiply the answer by 2? @AlexandervonHumboldt2

Answer 10

the distance formula is not necessary :)
see the equation that pooja has given you?

she has even plugged in (x1, y1) = (6, 3)
and resulting (x , y) = (-3, 4)
so we are trying to find the (x2, y2)

can you take a look at the equation pooja just gave ans see if you can solve for x? :)

Answer 11

Here it is again
\[\bf\Large \frac{x-6}{2} = -3\]

Answer 12

That really doesn't help @sleepyhead314

Answer 13

what part are you still confused on then? :)

Answer 14

Here see if thinking about it like this helps.
\[\huge~\rm~\frac{ 1 }{ 2 }x+\frac{ -6 }{ 2}=-3\]

Answer 15

What is -6/2?
