If 'X' represents the number of ends in a line and 'Y' represents the number of ends in a line segment, what is the value of 'Y−X' ?
Number of ends in a line = 0 = X
Number of ends in a line segment = 2 = Y
∴Y−X=2−0=2
If number of ends in a line is 'X' and the number of ends in a line segment is 'Y', what is the value of 'Y−X'?
