(-27,16)
Explanation of Solution
Given information:
Coordinates of midpoint M (-4,8) and Y(19,0)
Formula used:
Mid-point
For
Calculation: let the coordinates of midpoint M(-4,8) be X and Y
Also let the coordinates of Y be
Substituting values in the formula
Using cross multiplication
Subtracting nineteen both sides
Now for another coordinate of Y
Substituting values in the formula
Using cross multiplication method
Therefore missing coordinates are M(-27,16)
