Any line with no slope is parallel to the<br><br> *x-axis<br> *y-axis<br> *line y = x
Aleks04 [339]
The x-axis.

In the form Y = mx + b

m is the slope, so no slope means that my is zero so that means x is zero also.

So you would end up with

y = b so that means y will always be that value and the only thing that will change is the x value. This will create a horizontal lines that is parallel to the x-axis
