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
