Answer 2

(-1 , -1)

Explanation:

let D be the missing point

D lie on the line that passes through the point A and parallel to the line BC

D lie on the line that passes through the point C and parallel to the line AB

Then D is the intersection of those two lines

Then D is the point of coordinates (-1 , -1)
