Question

Find the coordinates of a midpoint, AB.. A (12,-7) & B (-4,7)

Answer 1

midpoint... is the average of the x's and average of the y's

x = (12 +(-4))/2 = 4 y(-7 + 7)/2 = 0

Answer 2

k...

Answer 3

@Kreshnik i tried .

Answer 4

what have you tried ? :P

Answer 5

to understand . See he didnt even show me how lol .

Answer 6

yes he showed you how...
he even did it for you !

ok
the formula is
\[\LARGE \left( {\frac{{{x_1} + {x_2}}}{2},\frac{{{y_1} + {y_2}}}{2}} \right)\]
now you have:
x_1=12
x_2=-4
and
y_1=-7
y_2=7
substituting you'll have the above result
