If x equals a constant number, the graph will be a vertical line. For example, the graph of x = 5 would be a vertical line that goes through the point (5,0). x equals 5 on every point along this lines.
0 5 /--------------/-----•------/
It is a horizontal line 5 units above the x-axis.
That line is horizontal on the graph. Its slope is zero.
The figures are exactly the same, but every point on the first graph is exactly 13 below the corresponding point on the second one.
y= -5
If x equals a constant number, the graph will be a vertical line. For example, the graph of x = 5 would be a vertical line that goes through the point (5,0). x equals 5 on every point along this lines.
Go what equals 5 units to the left
0 5 /--------------/-----•------/
-5
5
Since no points were given, for any point (x,y), plug the x and y values of the point into the equation. If you get a contradiction, ie 5=3 or something similar, then the point does not lie on the graph.

No.
The figures are exactly the same, but every point on the first graph is exactly 13 below the corresponding point on the second one.
The graph of x=5 is a vertical line on a set of coordinate axes that intercepts the x-axis at 5. Its slope is undefined.
