Question

Which equation represents the vertical line shown on the graph?

A. x - 4 = 0
B. x + 4 = 0
C. y - 4 = 0
D. y + 4 = 0

Answer 1

The equation that represents a vertical line on the graph is x + 4 = 0 (option B).

Step-by-step explanation:

The equation that represents a vertical line on the graph is x + 4 = 0 (option B).

When a line is vertical, it is parallel to the y-axis, and its equation will be in the form x = k, where k is a constant. In this case, the line is parallel to the y-axis and passes through the point (-4, 0). Therefore, the equation is x + 4 = 0.
