The line corresponding to y - 4 = 0 It has the following characteristic:

a. It is a horizontal line.

b. It is a vertical line.

c. It is a line with a positive slope.

d. It is a line with a negative slope.

A

Step-by-step explanation:

The equation of a horizontal line, parallel to the x - axis is

y = c

Where c is the value of the y - coordinates the line passes through.

Given

y - 4 = 0 (add 4 to both sides)

y = 4

This is the equation of a horizontal line

It is a horizontal line parallel to x axis
