Question

graph the line ( x = - 7 ).

Explanation:

Step1: Understand the nature of the line \(x = - 7\)

The equation \(x=-7\) represents a vertical line. For a vertical line \(x = a\), the \(x\)-coordinate of every point on the line is \(a\), and the \(y\)-coordinate can be any real number.

Step2: Locate \(x=-7\) on the \(x\)-axis

On the given coordinate - plane, find the point where \(x = - 7\). This is 7 units to the left of the origin (since \(x=-7\)).

Step3: Draw the line

Draw a straight vertical line passing through the point \(x = - 7\) on the \(x\)-axis. This line is parallel to the \(y\)-axis.

Answer:

Draw a vertical line passing through the point \((-7,0)\) on the \(x\)-axis. The line is parallel to the \(y\)-axis and all points on the line have the form \((-7,y)\) where \(y\in R\) (the set of all real numbers).
