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.
