Question

8
which graph represents the equation ( x = - 3 )?

Explanation:

Step1: Analyze the equation type

The equation \(x=-3\) is a vertical - line equation.

Step2: Recall vertical - line property

For a vertical line \(x = a\), all points on the line have an \(x\) - coordinate equal to \(a\), and the line is parallel to the \(y\) - axis.

Step3: Identify the correct graph

Among the given options, the graph of a vertical line at \(x=-3\) (the fourth option) satisfies the equation \(x = - 3\) as it has all points with \(x\) - value equal to \(-3\) for any \(y\) - value.

Answer:

The fourth option (the vertical line at \(x = - 3\))
