Raj plotted point L in the coordinate plane below. On a coordinate plane, point L is 1.5 units to the left and 4 units up.

He says that the plotted point is (4, negative 1.5). What is Raj’s error?
The x-coordinate should be -4.
The y-coordinate should be 1.5.
The x- and y-coordinates are switched.
Both coordinates should be positive.
