Oh, dude, if every point on a line has the same x coordinate, that means the line is vertical! It's like the line is standing at attention, with all its points stacked on top of each other in a straight up and down fashion. So yeah, in math lingo, we call that a vertical line with an equation like x = a, where 'a' is the x coordinate all the points share. Cool, right?
No. It changes by double the (perpendicular) distance from the point to the line.
A translation.
y = -xThe slope of the line is -1, and its y-intercept is zero.The graph is a 45-degree line, sloping down to the right, and passing through the origin.The 'x' and 'y' coordinates of every point are the same number, but every point has onepositive coordinate and one negative coordinate. That's exactly what the equation issaying.
Substitute the x coordinate into the equation for x and calculate y. If the formla gives the same y value as the coordinates, the point is on the line. If it is diffent, it is not on the line.
A line is undefined because all points on the line have the same x-coordinate.
No. It changes by double the (perpendicular) distance from the point to the line.

To find out the coordinates of a point in the coordinate system you do the opposite. Begin at the point and follow a vertical line either up or down to the x-axis. There is your x-coordinate. And then do the same but following a horizontal line to find the y-coordinate.

No. Every point on a contour line has the same elevation.
An equation with an undefined slope is typically in the form x = a, where 'a' is a constant number. This indicates a vertical line on the coordinate plane, where every point on the line has the same x-coordinate and no defined slope because the line is perfectly vertical.
No. In an ordered pair for a point in the xy-plane the first number is the x-coordinate and the second is the y-coordinate. (2, 5) is the point with an x-coordinate of 2 and a y-coordinate of 5; (5, 2) is the point with an x-coordinate of 5 and a y-coordinate of 2. Only if the x- and y- coordinates are equal are the points the same point. However, the point (5, 2) is the reflection of the point (2, 5) in the line y = x.
The origin is (0, 0), so the x-coordinate of the origin is 0. The point is located somewhere along the line x = 0, which is called the y-axis.
They are the same line.
Substitute the x coordinate into the equation for x and calculate y. If the formla gives the same y value as the coordinates, the point is on the line. If it is diffent, it is not on the line.
Every point on a given contour line is at the same elevation. Neighboring contour lines are at different elevations.
... point on the other side of the line at the same distance from the lien.
