Question

Write the equation of a vertical line that passes through the point (–4, 4).

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

Answer 1

We know a vertical line means that x = something. So, now that we know that, we can just use the point to get the answer. To do this, we take the x value of the equation, as it is the y value that is changing, and the x is constant. This gives us a final answer of D) x = -4.

Answer 2

a vertical line is represented by x = a number, with that number being the x coordinate of ur points.

so ur answer is : x = - 4
