Sometimes they do, sometimes they don't.
It depends upon which quadrant the point is in:
- In quadrant I they both have the same sign - positive;
- In quadrant II they have the different signs - x is negative whilst y is positive;
- In quadrant III they both have the same sign - negative;
- In quadrant IV they have the different signs - x is positive whilst y is negative;

What points are on the line given by the equation y equals x?
Y Equals X PointsAll points that has the same y coordinates as x coordinates are on the y=x line.
How does a reflection across the y axis change the coordinates of a point?
Reflection across the y-axis changes the sign of the x - coordinate only, that is, (x, y) becomes (-x, y).
How do you determine x and y in the same mathematical problem?
substitute 0 for y and solve for x. then substitute x for 0 and solve for why and you have the x and y coordinates
How do you rotate a figure 90 degrees counterclockwise?
The formula is (x,y) -> (y,-x). Verbal : switch the coordinates ; then change the sign of the new x coordinate. Example : (2,1) -> (1,-2)
How do you use absolute value to find the distance between two points that have the same x coordinates?
It is simply the difference between their y coordinates.
Do the x- and y- coordinates have the same sign?
Yes
What points are on the line given by the equation y equals x?
Y Equals X PointsAll points that has the same y coordinates as x coordinates are on the y=x line.
Which word means the same as x coordinate?
In algebra and mathematics , names are given to x coordinates and y coordinates as : x coordinates are known as abssisca. Y coordinates are known as ordinate.
In which quadrants do the x and y coordinates have the same signs?
The x and y coordinates are both positive in Q I. They are both negative in Q III
How does a reflection across the y axis change the coordinates of a point?
Reflection across the y-axis changes the sign of the x - coordinate only, that is, (x, y) becomes (-x, y).
How can you tell that the line segment connnecting the points is vertical without graphing the points?
The equation does not have and y variable in it: it is of the form x = c. Alternatively, the x coordinates of both points are the same and the y coordinates are not.
When reflecting a figure in the x-axis will you change all of the figures X coordinates or the y coordinates?
The y-coordinates.The y-coordinates.The y-coordinates.The y-coordinates.
How do you determine x and y in the same mathematical problem?
substitute 0 for y and solve for x. then substitute x for 0 and solve for why and you have the x and y coordinates
How do you rotate a figure 180 degrees clockwise about origin?
To rotate a figure 180 degrees clockwise about the origin you need to take all of the coordinates of the figure and change the sign of the x-coordinates to the opposite sign(positive to negative or negative to positive). You then do the same with the y-coordinates and plot the resulting coordinates to get your rotated figure.
Which comes first x axis or the y axis in math?
It is the x coordinates followed by the y coordinates i.e (x, y)
In which quadrant do the x- and y-coordinates have the different sign?
Upper left(Second) and lower right(Fourth).
Do rectangular coordinates have the same property as polar coordinates?
Some of them but not all. For example, uniqueness. The rectangular coordinates (x, y) represent a different point if either x or y is changed. This is also true for polar coordinate (r, a) but only if r > 0. For r = 0 the coordinates represent the same point, whatever a is. Thus (x, y) has a 1-to-1 mapping onto the plane but the polar coordinates don't.
