<u>Answer:</u>
Zero
<u>Step-by-step explanation:</u>
When a line is horizontal or you can say parallel to the x-axis, its slope is zero.
The reason being that there is no change in the value of y because the value of x is constant at each point of the line.
Slope = (change in y) / (change in x)
On the contrary, the slope of the line which is vertical or parallel to the y-axis has an undefined slope.
