What are the coordinates of point B?
zaharov [31]

Point a is at (-2,4) => (x1,y1)

Midpoint is (2.5, 3.5) => (a,b)

Point B is (x2, y2)

To find midpoint we use formula

(a=\frac{x_1+x_2}{2} , b= \frac{y_1+y_2}{2})

a= 2.5, b= 3.5, x1= -2  and y1= 4

Plug in all the values and findout x2, y2

(2.5=\frac{-2+x_2}{2} , 3.5= \frac{4+y_2}{2})

multiply 2 on both sides to remove fraction

(5 = -2+x2 , 7 = 4+ y2)

5 = -2+x2, so x2= 7

7 = 4+ y2, so y2= 3

The point B is ( 7, 3)
