You can put this solution on YOUR website! It has no slope.
It has no y-intercept.
If you have to fit your answer into a box, the expected entry is probably "undefined", although I would accept "N/A" to.
The graph of the line is this blue line:
There is no y-intercept, because the line is parallel to the y-axis,
and the y- intercept would be the y-coordinate of the point where the line crosses the y-axis.
There is no slope, because the lslope is the increase in when increases bt .
and for that line never increases, because all over the line.
