Find the Domain 3x+5y+45=0

Problem

3*x+5*y+45=0

Solution

1. Identify the type of equation. This is a linear equation in two variables, x and y 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=0 there are no square roots of negative numbers, no denominators that could be zero, and no logarithms.

3. Define the domain. Since there are no restricted values for x the variable x can be any real number.

4. Express the domain using interval notation. The set of all real numbers is represented as (−∞,∞)

Final Answer

Domain:(−∞,∞)
