Question

M(5,7)is the midpoint of the line segment joining A(3,4) to B.find the coordinates of B.​

Answer 1

B(7;10)......look at the picture

Answer 2

Answer:

B(5, 7)

Step-by-step explanation:

Midpoint formula is given as

$m(5, 7)= (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})$  ------------(1)

Here

$(x_1, y_1)=(3, 4)$

Suppose point B is $(x_2, y_2)$

Substituting value sin equation (1)

$(5, 7) = ( \frac{3+x_2}{2} , \frac {4+y_2} {2} )$

$5 = \frac{3+x_2}{2} \\7 = \frac {4+y_2} {2}$

$x_2 = 7$

$y_2 = 10$
