Find the Domain x-2y=6

Problem

x−2*y=6

Solution

1. Identify the type of equation. The equation x−2*y=6 is a linear equation in two variables, which represents a straight line in the Cartesian plane.

2. Solve for y to express the equation in slope-intercept form. Subtract x from both sides.

−2*y=−x+6

3. Divide both sides by −2 to isolate y

y=1/2*x−3

4. Determine the domain. In a linear function of the form y=m*x+b there are no square roots of negative numbers, no divisions by zero, and no logarithms. Therefore, the independent variable x can be any real number.

5. Express the domain in interval notation. Since x can be any value from negative infinity to positive infinity, the domain is (−∞,∞)

Final Answer

Domain: *(−∞,∞)
