We can use algebraic operations to rewrite expressions, including polynomial expressions. When we rewrite polynomial expressions
, the representations look different but still represent the same expression. Where else have you seen this type of transformation—when something appears different, but its meaning remains the same?
Similar transformations to the application of algebraic operations to rewrite expressions that form representations that appear different from their parent expressions, can be seen in the following fields;
Geometry; Rigid transformations such as rotation, can transform a rectangle to appear to look like a kite
Physics; The heating of a liquid, can transform its physical state from liquid to gas, however, the gas formed by heating the liquid represent the same material chemically
The slope is the difference in the y coordinates divided by the difference in the x coordinates so you have to divide 6 by 3 since they have already given you the difference.
