it means that the line in the linear equation is a vertical line
A vertical line on a graph has an infinite slope, and no y-intercept.
No. The equation x=7 has an undefined slope since it is simply a vertical line located at x = 7. A basic test for a function is if you can draw a vertical line through the graph of the equation and it touches in more than one place, it is NOT a function.
Yes, a vertical line is linear, but it is not a function, because every point on the line has the same x value.
A horizontal line is perpendicular to a vertical line.
