Identify the quadrants of the following points A(-2,4) (b) B(7,-5)​

Hi, 
In first quadrant both x-coordinate and y -coordinate are positive
and in second quadrant x-coordinate is negative and y -coordinate is positive
so (-2,4) lie on second quadrant
and in fourth quadrant ​ x-coordinate is positiveand y -coordinate is negative 

so (7,-5) lies in fourth quadrant
