Question

look at this graph:
write the equation of the line.

Explanation:

Step1: Identify line type

The graph shows a vertical line. Vertical lines have an undefined slope and their equation is of the form \( x = a \), where \( a \) is the x - coordinate of any point on the line.

Step2: Determine the x - value

Looking at the graph, the vertical line passes through points where \( x = 6 \) (for example, when \( y = 0 \), \( x = 6 \); when \( y = 8 \), \( x = 6 \), etc.). So the equation of the line is \( x = 6 \).

Answer:

\( x = 6 \)
