Well this is my thought depending on where the point of dilation is the coordinates of the give plane is determined. The point of dilation not only is main factor that positions the coordinates, but the scale factor has a huge impact on the placement of the coordinates.

Describe the coordinates of all points in all the quadrants?
The coordinates of all points in the coordinate plane consist of ordered pairs of numbers.
What are two coordinates that make a positive slope?
Two coordinates define a point. You need two pairs of two coordinates to define two points and, therefore, a slope.
Is the slope always positive if the coordinates of two points on the line are positive?
No.
How do you use absolute value to find the distance between two points that have the same x coordinates but?
It is simply the difference between their y coordinates.
What is the slope of the line connecting the points 325 and 3520?
You need two coordinates, not one, to specify a point. To calculate the slope, simply calculate (difference in y-coordinates) / (difference in x-coordinates).
What are the coordinates of the midpoint of GH with end points?
-- 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.
Describe the coordinates of all points in all the quadrants?
The coordinates of all points in the coordinate plane consist of ordered pairs of numbers.
Which properties are preserved under dilation?
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.
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.
Points where lines meet?
Intersection or coordinates
How is plotting of points done?
By giving their coordinates.
When graphing the points can your tell whether or not they are collinear?
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.
Do points have length but no height in geometry?
On the Cartesian plane points have coordinates of length and height
What are pairs of numbers that show points on a graph?
Coordinates.
Which methods can you use to get the y coordinates of a midpoint?
Take the arithmetic average of the y-coordinates of the end points.
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.
What is the slope of the coordinates -3 4 4 -4?
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.
