A Simple Coordinate System

Changing the Scale of an Axis
This coordinate system has a one-to-one relationship between unit lengths on the X- and Y- axes. Change the scale so the maximum X-value becomes 100.
The line looks like it is in a new position, but the
	slope is different
	intercept is different
	points on the line have different coordinates
	slope, the intercept, and the coordinates of all points remain the same
