Question

A VERTICAL line passes through the point (4, 5). Find an equation for this line.

A)
X = 4
B)
y = 5
C)
y = 4
D)
y = 4x + 5

Answer 1

A

Explanation:

The equation of a vertical line parallel to the y- axis is

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (4, 5 ) with x- coordinate 4 , then

x = 4 ← equation of vertical line → A
