The coordinates of all points in the coordinate plane consist of ordered pairs of numbers.
Two coordinates define a point. You need two pairs of two coordinates to define two points and, therefore, a slope.
No.
It is simply the difference between their y coordinates.
You need two coordinates, not one, to specify a point. To calculate the slope, simply calculate (difference in y-coordinates) / (difference in x-coordinates).
-- The 'x' coordinate of the midpoint is the average of the 'x'-coordinates of the end-points. -- The 'y' coordinate of the midpoint is the average of the 'y'-coordinates of the end-points.
The coordinates of all points in the coordinate plane consist of ordered pairs of numbers.
Properties such as parallelism, ratio of distances, and the measure of angles are preserved under dilation. This means that parallel lines remain parallel after dilation, the ratio of lengths between corresponding points remains constant, and angles maintain their measures before and after dilation.
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.
Intersection or coordinates
By giving their coordinates.
Yes. Calculate the ratio of the difference in y-coordinates and the difference in x-coordinates between pairs of points. If the ratio is the same, the points are collinear. If not, they are not. The only exception is if all the x-coordinates are he same and the ratio is not defined. In this case the points are also collinear - all on a vertical line.
On the Cartesian plane points have coordinates of length and height
Coordinates.
Take the arithmetic average of the y-coordinates of the end points.
Y Equals X PointsAll points that has the same y coordinates as x coordinates are on the y=x line.
The slope for a line between two points is (difference of y-coordinates) divided by (difference of x-coordinates). That is, (y2-y1)/(x2-x1). It doesn't matter in what order you take the points.
