Question

The graph of the line y = 4 is a

A) vertical line with a slope of zero.
B) horizontal line with a slope of zero.
C) vertical line with an undefined slope.
D) horizontal line with an undefined slope.

Answer 1

The answer would be B

Answer 2

horizontal line with a slope of zero.

Explanation:

The graph of the line y = 4 is a

when we graph y=4, we get a line at y=4

the graph of y=some number gives us a horizontal line

the graph of x= some number gives us a vertical line at that number

y=4, is the graph of a horizontal line at 4. for all horizontal lines the slope is 0

for all vertical lines the slope is undefined

for y=4 , the slope of the line is zero

horizontal line with a slope of zero.
