Find the Domain 6x-9y=18

Problem

6*x−9*y=18

Solution

1. Identify the type of equation. This is a linear equation in two variables, which represents a straight line in the Cartesian plane.

2. Determine the constraints on the variables. In a linear equation of the form A*x+B*y=C there are no square roots of negative numbers, no denominators containing variables that could result in division by zero, and no logarithms.

3. Conclude the domain. Since x can be any real number without violating any mathematical rules, the domain is the set of all real numbers.

Final Answer

Domain: *(−∞,∞)
