This document provides instructions and examples for finding the slope and y-intercept of a line from its equation, ordered pairs, or graph and using them to graph the line. It explains that slope is defined as rise over run and is used along with the y-intercept to graph lines by standard form, plotting the y-intercept and using slope to find successive points. Exercises are provided to have students practice finding slope, y-intercept, and graphing lines from different representations.

Slope = ----------------------- = ---------------------------------------<br />EX2: What is the slope of the following graph?<br />What is the y-intercept of this graph?<br />EX3:What is the slope of the line going through the ordered pairs (4, 2) and (-3, 16)?<br />The most common form for a linear equation is called __________________________________.<br />The equation for this form is: ________________________________<br />x represents the _________________________

2. y represents the _________________________

3. m is the _____________________ of the line

4. b is the ___________________________________To graph a line in this form:<br />Plot the _______________________________ first. (It’s the one point on the line that you already know.)

5. _____________________________________________, use the slope to rise and run to the next point.
