Complete question:

Which of the following represents "The sum of the abscissa and the ordinate is six"? 

x + y = 6 
xy = 6 
6xy

x + y = 6 

X is abcissa, and y presents ordinate. So logically, their sum will be 6. 

Answer:

x+y=6

Step-by-step explanation:

In two dimensional graph we have 4 quadrants with two mutually perpendicular lines cutting the region into 4 quadrants.

The x coordinate of any point is called abcissa and y coordinate of the point is ordinate.

Sum of abscissa and ordinate = x+y when written as an algebraic expression

Since given that The sum of the abscissa and the ordinate is six

we have as

x+y =6

Hence answer is

x+y =6
