Question

The midpoint of VW is M(-1, -2). One endpoint is W(4,4) Find the coordinates of endpoint V.

Answer 1

Step-by-step explanation:

By mid point formula

coordinate of M = (x1 + x2) /2 , (y1+y2) / 2

-1,-2 = (x1 + 4)/2 , (y1+4)/2

equating the x coordinate

-1 = (x1+4)/2

-2 = x1+4

-6 = x1

equating the y coordinate

-2 = (y1+4)/2

-4 = y1+4

-8 = y1

therefore, coordinate of V is (-6,-8)
