Linear Combinations of Unit Vectors

Let u be the vector with an initial point (-2, 1) and terminal point (3,-2). Write u as a linear combination of the standard unit vectors I and j. Use spaces in between the values and the subtraction sign. For example, do not enter 5i-6j. Instead, use spaces to enter 5i - 6j.
