The websites to consider...

Use this site for some of the questions.  This provides an introduction to the design and information regarding the slope-intercept for of a line. 


The following questions can be answered using this page, which goes into further detail about linear equations.


Use this page to manipulate the slope and y-intercept of linear equations to see how these values affect the resulting graph.


Should either these sites fail, read through this site (consists of three pages) to get your information


Reflect on your explorations and research when answering these questions:


1)  First, consider the slope of a vertical line.  Justify in your own words why the slope of a vertical line is what it is.


2)  Design several linear equations in slope-intercept and describe them graphically using proper terminology.


3)  Consider the point-slope form of a line and the slope-intercept form of a line.  Explain how we can arrive at the slope-intercept form of a line from the point-slope form of a line.
