Introduction to Coordinate geometry
The things you will learn to do:
1. Determine the distance between two points
a. for two points that lie on a horizontal line*
b. for two points that lie on a vertical line*
c. for two points that lie on an oblique line*
*note: The line does not necessarily need to be drawn in.
Determine the length of a segment.
Choose two random points, A and B, on the graph above. Find the distance between them.
Determine midpoint of a segment
Calculate the coordinates of the midpoint of A and B.
Slope of a line segment
Calculate the slope of a line passing through points A and B.
Slope of the line segments parallel to AB.
Calculate the slopes of line segments parallel to AB.
Slope of the line segments perpendicular to AB.
