Select the correct answer.
Aneli [31]

Answer:

B. x = -6

Step-by-step explanation:

A line with the equation, y = ¼, is a horizontal line. Therefore, the line that is perpendicular to it would be a vertical line, which can be represented by the equation, x = a. Where, a is the x-value or the point where the vertical line intersects the x-axis. This x-coordinate remains the same for every point on the vertical line.

Thus, since the perpendicular line passes through (-6, -9), therefore, the value of a = -6.

Thus, the equation of the perpendicular line would be:

x = -6
