Answer:
The coordinates of the fourth vertex are (9, -6).
Explanation:
To find the coordinates of the fourth vertex of the parallelogram, we can use the fact that opposite sides of a parallelogram are parallel and equal in length.
Let's start by finding the vector from the first vertex to the second vertex:
v = (3, -4) - (-2, 7) = (5, -11)
Now, let's add this vector to the third vertex to find the fourth vertex:
(4, 5) + (5, -11) = (9, -6)
Therefore, the coordinates of the fourth vertex are (9, -6).
