Final answer:

The correct answer is option C. 'Substation' (likely a typo for 'substitution') which is not a component of the solution line itself, whereas the other options are typical components used in solving a linear equation.

Step-by-step explanation:

The question is asking which option is not a component of a solution line when solving linear equations. A solution line usually refers to a set of all possible solutions to a linear equation, typically represented graphically. When solving for the solution to a linear equation, the following are necessary components:

  • An equal sign (=) which indicates that two expressions are equal.
  • A value, which could be a numerical value that a variable is equal to.
  • A variable, such as x or y, which represents an unknown quantity that we are solving for.
  • An inverse operation, such as addition or subtraction, used to isolate the variable and solve the equation.

The option that is not a typical component of a solution line is Substation, which appears to be a typo but likely meant to be 'substitution'. While substitution is a method used to solve systems of equations, it is not a component of the solution line itself.
