Answer:
horizontal line with a slope of zero.
Step-by-step 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.
