Question

Write a program to ask for a Cartesian coordinate x,y. Your program should read in an x value and a y value and then inform the user whether it is the origin (0,0), on the y axis, eg (0, 10), on the x axis, eg (-3,0) or in which quadrant it appears.

Answer 1

The program in Python is as follows:

x = int(input("x: "))

y = int(input("y: "))

if x == 0:

if y == 0: print("Origin")

else: print("y axis")

elif x>0:

if y > 0: print("First Quadrant")

elif y < 0: print("Fourth Quadrant")

else: print("x axis")

elif x < 0:

if y > 0: print("Second Quadrant")

elif y < 0: print("Third Quadrant")

else: print("x axis")

Step-by-step explanation:

These get input for x and y

x = int(input("x: "))

y = int(input("y: "))

If x is 0

if x == 0:

............ and y is 0, then the point is at origin

if y == 0: print("Origin")

............ and y is not 0, then the point is on y-axis

else: print("y axis")

If x is greater than 0

elif x>0:

............ and y is greater than 0, then the point is at in the first quadrant

if y > 0: print("First Quadrant")

............ and y is less than 0, then the point is at in the fourth quadrant

elif y < 0: print("Fourth Quadrant")

............ Otherwise, the point is on the x axis

else: print("x axis")

If x is less than 0

elif x < 0:

............ and y is greater than 0, then the point is at in the second quadrant

if y > 0: print("Second Quadrant")

............ and y is less than 0, then the point is at in the third quadrant

elif y < 0: print("Third Quadrant")

............ Otherwise, the point is on the x axis

else: print("x axis")
