E.

• Notice that the solution is the same as the coordinates of point A.

Tip

• Try using this drag and drop method to find the point of intersection of two lines. This is a great

way to find the solution to a system of equations.

• To view a fractional result as a decimal, tap the input row and then u.

• The information that appears when you drop a figure into another application depends on the
