Answer: The line y=3 is a horizontal line, and a horizontal line has a slope of zero. The only lines parallel to a horizontal line are other horizontal lines. Therefore, there is no slope.

Step-by-step explanation: y=3 rewritten as y=0x+3

For a line equation for the form of y=mx+b, the slope is m

m=0

Answer:

The slope is zero.

Explanation:

Imagine the graph.
y=3 would simply be a horizontal line. All horizontal lines have slopes of 0. You can also use the slope formula if necessary to try it out.

On the other hand, if the line was vertical (e.g.
x=3), then the slope would be undefined.
