[color=#1e84cc][b]Recall that the slope of a line is a number that simply tells us how STEEP that line actually is. [br][/b][/color][color=#1e84cc]You've already learned that slope is the RATIO of the RISE to the RUN between any two points that lie on the line. [/color][br][br][color=#980000][b]Here may be a more meaningful interpretation of the phrase "slope of a line" for some of you:[/b][/color] [br][br][color=#9900ff][b]The slope of a line[/b][/color] is the [color=#9900ff][b]amount by which the output (y-value) of the line changes[/b][/color] [b]when the input (x-value) increases by 1 unit.
