Question

6 multiple choice 10 points what is the equation of a vertical line through the point (4, -5)? x = -5 x = 4 y = -5 y = 4

Explanation:

Step1: Recall vertical line equation

A vertical line has an undefined slope and its equation is of the form \( x = a \), where \( a \) is the x - coordinate of any point on the line.

Step2: Identify the x - coordinate

The given point is \( (4,-5) \). The x - coordinate of this point is 4. So, the equation of the vertical line passing through \( (4,-5) \) should be \( x = 4 \).

Answer:

B. \( x = 4 \)
