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(5, 7)

Explanation:

Midpoint formula is given as

`m(5, 7)= ((x_1+x_2)/(2) , (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) = ( (3+x_2)/(2) , \frac {4+y_2} {2} )`

`5 = (3+x_2)/(2) \\7 = \frac {4+y_2} {2}`

`x_2 = 7`

`y_2 = 10`

Answer 2

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