Observe that when you graph straight lines, the lines slant in different directions. The measure of this slant is called the [color=#0000ff]slope, [/color]usually expressed as a ratio of two numbers: [color=#0000ff]rise/run[/color].[br][br]Grab one of the points and rotate it to complete a full circle. Observe the changes in the value of the fraction as well as the sign.
[b][color=#0000ff]QUESTION 1[/color][/b]: When is the slope a proper fraction? When is the slope a whole number? (Use rise and run in your answer.)
[color=#0000ff][b]QUESTION 2[/b][/color]: When is the slope positive and when is it negative? (Use directions such as: left, right, up, down in your answer.)[br]
