Answer:
The correct option: x + y = 6
Explanation:
In a Cartesian system or a coordinate system, the abscissa is the value of the horizontal (x) value and the ordinate is the value of the vertical (y) value.
So, The sum of the abscissa and the ordinate = x + y when written as an algebraic expression.
Since given that The sum of the abscissa and the ordinate is six
So, the correct equation is x + y = 6
