  1. this just means that you decide how steep a line is by the slope as if it were always positive 10/18/2010 - SLOPE UNIT 3 - Textbook 5.1 ·Slope describes how steep the line is. (the greater the absolute value of the slope the steeper the line) ·Slope of a line is determined by any 2 points on the line.

  2. As usual the textbook can help you! This is Section 5.1

  3. Use Rise Run to find the slope. negative positive zero undefined NOTICE: ON (zero over a number) - zero slope NO (a number over zero) - undefined aka No slope

  4. There are 2 formulas to find slope: Rise over Run as reviewed already PLUS... *** write this formula down***

  5. CLASSWORK AND HOMEWORK - PW 5-1 #1-10 End of lesson 10/18

  6. LESSON 10/19 & 10/20 - go over Monday's homework, then Tuesday's handout, then we started Wedn. lesson. Monday homework.

  7. negative zero positive undefined

  8. 3/11 positive -1/10 negative -2/3 negative 5/1 positive 0/6 zero 8/0 undefined

  9. 11. 7/1 12. 5/3 13. -5/2 14. undefined 15. -6/7 16. 0/-5 zero slope

  10. WEDNESDAY LESSON WAS GRAPHING USING ONE POINT AND SLOPE Draw the line that ..... 3) has a slope of -1/3 and passes through (4,-3) 1) has a slope of 3/4 and passes through (2,5) up 3 over 1 up 3 over 4 DOWN 3 over 1 2) has a slope of 3 and passes through (-1,2) 1ST - GRAPH THE POINT GIVEN. 2ND - Using slope, rise then run to the next point. 3RD - connect the points and make a line

  11. classwork - 10/20

  12. homework handout given. Slope worksheet #3

  13. 10/21/2010 Quiz TOMORROW - 15 total problems: KNOW THE 2 SLOPE FORMULAS! 3 find slope given 2 points 3 find slope from a graph 3 tell is slope is pos., neg., zero, or undefined 3 graph a line given one point and the slope 1 rate of change problem using a table 1 rate of change problem using a graph 1 multiple choice.

  14. CHECK YOUR ANSWERS TO YESTERDAY'S HANDOUT

  15. **I don't need to finish the bottom since top is zero

  16. OR

  17. last new lesson for Section 5-1 Next we're going through problems from your textbook (pg 258) where SLOPE is defined as the RATE of CHANGE change in dependent variable change in independent variable = 1st - To find slope start with a table... 2nd - To find slope change the table to points and use the slope formula

  18. Find the rate of change for each 2 year period. Use the rate of change to determine at what time Karen grew the most.

  19. if time 1st - To find slope start with a table... 2nd - To find slope change the table to points and use the slope formula

  20. Is it any different when we are given the information in an equation?

  21. Classwork - Odd problems We will work these until the bell!

  22. BONUS for tomorrow

  23. extra practice, if time... WARM-UP

  24. MORE PRACTICE - if time slope formula: y2 - y1 x2 - x1 Find the slope of the line that passes through the given points, WITHOUT GRAPHING. 1. (1,6) and (3,13) 2. (0,3) and (5,-7) 3. (-1,2) and (5,0) HOMEWORK complete handout
