A) y = 4
B)y = x – 0
C)y = x + 0
D)x = 4

Answer 1

hello :
answer A) y = 4 because the slope = 0

Answer 2

Answer:A) y = 4

Explanation:

The slope of any horizontal line is zero, 0 .The equation of any horizontal line is of the form = b, where b is the y-coordinate of the y-intercept .

Among all the options given The equation y=4 represent a horizontal line .

The equations y=x-0 ,y=x+0 represent the same line y=x and are not horizontal lines. x=4 is a vertical line.

Option A y=4 represent a horizontal line.
