### A2 2 linear fxns notes

1. 1. Algebra 2<br />Slope<br />EX1:Find the intercepts of the line y=3x-9. Then graph the line. <br />32004004191000<br />Slope<br />How is slope defined? 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 /><ul><li>x represents the _________________________
2. 2. y represents the _________________________
3. 3. m is the _____________________ of the line
4. 4. b is the ___________________________________</li></ul>To graph a line in this form:<br /><ul><li>Plot the _______________________________ first. (It’s the one point on the line that you already know.)
5. 5. _____________________________________________, use the slope to rise and run to the next point.
6. 6. _______________________________ with a line.</li></ul>320040022161500EX4:Graph the line y=23x-1.<br />HW “Line graph intuition” and “Slope of a line” exercises on Khan Academy<br />
