Answer:
This is a vertical line whose "equation" is x = 9
Ax + By = C
A = 1
B = 0
C = 9
1x + 0y = 9 or x = 9
Explanation:
The graph shows a vertical line intersecting the x axis at 9. A vertical line is telling us that x is always 9, regardless of the value of y. This reduces the standard form of Ax + By = C to simply x = 9. y plays no role in this line, A is 1, B is 0, and C is 9
Ax + By = C
1x + 0y = 9 or x = 9
