  1. Algebra 2Lesson 2.3 Check:

  2. Warm-up:

  3. Answers

  4. 2.3 Graphing Lines • Objective: Students will use intercepts and slope intercept form to sketch a quick graph of a line.

  5. Notes 2.3Graphing Lines slope and y-intercept Watch the following examples, then We will practice on worksheet 2.1B

  6. Ex 1 Horizontal lines Y=3 Y=0 is the x-axis Y=-5

  7. Ex 2 Vertical Lines x=6 X=-4 X=0 is the y-axis

  8. Just watch y = 2x + 1 y = 2x + 1 Run 1 y-intercept Rise b = 1 2 slope m = 2

  9. EX 3 Graph y = -3x + 2 Run y = -3x + 2 1 y-intercept Rise b = 2 -3 slope m = -3

  10. Ex 4 Run 3 y-intercept b = -1 Rise 2 slope

  11. Run 2 y-intercept Rise b = 3 -1 slope

  12. Classwork Practice Worksheet 2.1 B (front and back) Get 1 sheet of graph paper and a Ruler Fold graph paper into ¼’s.

  13. x- and y- intercepts Graphing Lines (ongraph paper) Watch the following examples, then we Will try some on graph paper.

  14. Watch find the x value when y = 0 2x + 3y = 6 x-intercept 2x + 3(0)= 6 2x + 0= 6 2x= 6 find the y value when x = 0 y-intercept 2(0) + 3y= 6 0 + 3y= 6 3y= 6

  15. find the x value when y = 0 EX 5 4x - y = 6 x-intercept 4x - (0)= 6 4x - 0= 6 4x= 6 find the y value when x = 0 y-intercept 4(0) - y= 6 0 - y= 6 -y= 6

  16. EX 6 find the x value when y = 0 4x + 2y = 3 x-intercept 4x + 2(0)= 3 4x + 0= 3 4x= 3 find the y value when x = 0 y-intercept 4(0) + 2y= 3 0 + 2y= 3 2y= 3

  17. find the x value when y = 0 EX 7 3x - 2y = 7 x-intercept 3x - 2(0)= 7 3x - 0= 7 3x= 7 find the y value when x = 0 y-intercept 3(0) - 2y= 7 0 - 2y= 7 -2y= 7

  18. Assignments • Finish Notes on graph paper • Classwork: p. 92 # 11-14(on back of graph paper), 25, 29, 37 • Homework:P. 93 # 16-26 even, 36, 42, 60, 61 • Closure: What are the intercepts of the graph…
