I don't know if this is quite what you're looking for but I think it is a diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.
Hope this helps!
For 13, do 18÷45 and for 14 is 45 minutes exact
Quadrant 2 because it goes to the left because the X is negative then up because the Y is positive.
