Question #2d2fb

Answer 1

`(-7,0)`

Explanation:

We know that for two points `(x_1, y_1)` and `(x_2, y_2)` is the mid point has coordinates as:

`((x_1​​+x_2)/2,​​(y​_1​​+y_2)/2)`.....(1)

Inserting given values we get the equations
`((1​​+x_2)/2,​​(4+y_2)/2)=(-3,2)`
Comparing the two we get
`(1​​+x_2)/2=-3` .......(2)
`​​(4+y_2)/2=2` ......(3)

From (2)
`1​​+x_2=-6`
`=>x_2=-7`
From (3)
`​​4+y_2=4`
`​​=>y_2=0`
We get coordinates of point B as
`(-7,0)`
