What can you say about a line if every point on the line has the same x coordinate?

That the line has no slope.. as in it is completely vertical.. The equation for that line would be y=x

When a point is reflected over a horizontal line and is not on the line. Does the y-coordinate stays the same?
No. It changes by double the (perpendicular) distance from the point to the line.
Which transformation moves every point of a figure the same distance and in the same direction on a coordinate plane.?
A translation.
What is the answer and workings for this equation on plotting straight-line graphs y equals -x?
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.
How do you determine if a certain point lies on a given line by just having the coordinates for the point and the equation of the 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.
Why is a line undefined?
A line is undefined because all points on the line have the same x-coordinate.

How do you set up a cartesian plane?
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.

Is it true that every point on a contour line is at a different elevation?
No. Every point on a contour line has the same elevation.
Is the ordered pair 5 2 the same point as 2 5 in the xy-plane?
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.
Where is a point located if it has the same x-coordinate as the origin?
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.

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.
What are lines that overlap at every point when they are graphed?
They are the same line.
Every point on a contour line is at a different elevation?
Every point on a given contour line is at the same elevation. Neighboring contour lines are at different elevations.
When a point lies on the y-axis what do you know about it's x-coordinate .?
The x-coordinate of any point on the y-axis is 0. The y-axis is a line perpendicular to the x-axis. Any point on a line perpendicular to the x-axis has the same x-coordinate. The y-axis is the line perpendicular to the x-axis through 0, and has the equation x = 0; similarly, the x-axis is the line perpendicular to the y-axis through 0 and has the equation y = 0.
When a line of symmetry divides an image every point on one side of the line has corresponding?
... point on the other side of the line at the same distance from the lien.
