The coordinates of three vertices of a square are (1, –1), (6, –1), and (6, 4). Fill in each blank to make the statement true. a. What are the coordinates of the fourth vertex?
The coordinates of the fourth vertex are.

b. What is the area of the square?

The area of the square is.

the slope of the line is 60

one point on the line is (40,10)
