Question

graph the line that passes through the points (9, -2) and (9, -7) and determine the equation of the line.

Explanation:

Step1: Identify x-coordinate pattern

Both points have $x=9$.

Step2: Recognize vertical line type

Vertical lines have form $x=a$.

Step3: Assign constant x-value

Substitute $a=9$ into the form.

Answer:

The equation of the line is $x=9$, and the graph is a vertical line passing through $x=9$ that goes through the points $(9, -2)$ and $(9, -7)$ (as shown on the provided grid).
