(1 point) Suppose B= (-6, -7) and AB = (-7, 1). Then A = ■ ■ help (points) ■ A point must use parentheses and commas: (4.5, 3/7) is a valid

point in 2 dimensions. (pi, e, 2) is a valid point in 3 dimensions. If the answer is more than one point: Enter your answer as a comma-separated list of points, for example: (4,3), (5,10) ■ If there are no solutions: Enter NONE or DNE (this may vary from problem to problem) Examples of constants used in points: pi, e = e^1 Entering Angles ■ Functions may be used in each coordinate of a point, but may not be applied across the parentheses or commas: (sqrt(2),sqrt(5)) is valid, but (sqrt(2,5)) is not. ▪ Link to a list of all available functions /pg_files/helpFiles/Entering-Points.html
