What kind of correspondence there is between the points in the coordinate plane?
There are infinitely many possible correspondences between points in the coordinate plane. Some examples: Every point with coordinates (x+1, y) is one unit to the right of the point at (x, y). Every point with coordinates (x, y+1) is one unit up from the point at (x, y). Every point with coordinates (x, -y) is the reflection, in the y-axis of the point at (x, y).
How do you calculate the midpoint of a pair of coordinates in maths?
The average of the x coordinates of the point(s) is the x coordinate of the mid point, The average of the y coordinates of the point(s) is the y coordinate of the mid point, and so on, through 3, 4 dimensions, etc.
How do you rotate a figure on a graph 180 degrees?
If a point is at coordinates (x , y), then move it to (-x, -y).
What is defined to be the point of intersection of the -x and -y axes?
It is either the "origin of coordinates" or (more often abbreviated to) the "origin".
What does it mean on a graph when x equals 0?
When x = 0, the point that has (0, y) coordinates will be on the y-axis for any y.
Describe how to find the coordinates of the image of a point after a 270 degree rotation?
Point A has coordinates (x,y). Point B (Point A rotated 270°) has coordinates (y,-x). Point C (horizontal image of Point B) has coordinates (-y,-x).
What is the coordinates for y equals x y equals -x plus 2?
The coordinates of the point of intersection is (1,1).
What kind of correspondence there is between the points in the coordinate plane?
There are infinitely many possible correspondences between points in the coordinate plane. Some examples: Every point with coordinates (x+1, y) is one unit to the right of the point at (x, y). Every point with coordinates (x, y+1) is one unit up from the point at (x, y). Every point with coordinates (x, -y) is the reflection, in the y-axis of the point at (x, y).
How does reflection across the y-axis change the coordinates of the orignal point?
y' = y, x' = -x.
How do you reflect a figure across the y axis?
Replace each point with coordinates (x, y) by (-x, y).
How do you calculate the midpoint of a pair of coordinates in maths?
The average of the x coordinates of the point(s) is the x coordinate of the mid point, The average of the y coordinates of the point(s) is the y coordinate of the mid point, and so on, through 3, 4 dimensions, etc.
How do you rotate a figure on a graph 180 degrees?
If a point is at coordinates (x , y), then move it to (-x, -y).
What is the y-coordinates of a point where a graph crosses the y-axis?
The y-coordinate of every point on the x-axis is zero.
What is the x coordinate or y coordinate of a point is 0?
If you mean at the Origin (where both X and Y cross), then the coordinates would be (0,0)================================-- If the 'x' coordinate is zero, then the point is on t he y-axis.-- If the 'y' coordinate is zero, then the point is on the x-axis.-- If both coordinates are zero, then the point must be the onethat's on both axes ... the 'origin'.
What is defined to be the point of intersection of the -x and -y axes?
It is either the "origin of coordinates" or (more often abbreviated to) the "origin".
How do you find the equation of a parabola if you know the vertex and a point it passes through?
Use this form: y= a(x-h)² + k ; plug in the x and y coordinates of the vertex into (h,k) and then the other point coordinates into (x,y) and solve for a.
Give the coordinates of the point located halfway between 2 1 and 2 4?
The idea is to calculate the average of the x-coordinates (this will be the x-coordinate of the answer), and the average of the y-coordinates (this will be the y-coordinate of the answer).
