If the y coordinate does not change, it is a horizontal line.
cosine, sin* * * * *No. They are the horizontal or x-coordinate, called the abscissa; and the vertical or y-coordinate, called the ordinate.
It is a coordinate of x and y on the coordinate plane
For reflection in the x-axis, change the sign of the y-coordinate of every point.For reflection in the y-axis, change the sign of the x-coordinate of every point.
It is called the y intercept
If the y coordinate does not change, it is a horizontal line.
The first coordinate always is called the "x" coordinate, because it goes on the "x" axis, while the second coordinate is always called the "y" coordinate because it always goes on the "y" axis.
x-coordinate: abscissa y-coordinate: ordinate
its called an ordered pair. it is an x-coordinate and a y-coordinate (x,y)
The ratio of y/x is called the slope.
Since the x coordinate will change, but not the y coordinate, take (x,y) and reflect across the y axis and you have (-x,y)
cosine, sin* * * * *No. They are the horizontal or x-coordinate, called the abscissa; and the vertical or y-coordinate, called the ordinate.
It is a coordinate of x and y on the coordinate plane
For a reflection over the x axis, leave the x coordinate unchanged and change the sign of the y coordinate.For a reflection over the y axis, leave the y coordinate unchanged and change the sign of the x coordinate.
For reflection in the x-axis, change the sign of the y-coordinate of every point.For reflection in the y-axis, change the sign of the x-coordinate of every point.
It is called the y intercept
Other way around (X,Y)
