  1. Graphing Lines slope & y-intercept & x- & y- intercepts Jeffrey Bivin Lake Zurich High School Jeff.bivin@lz95.org Last Updated: September 6, 2007

  2. Graphing Lines slope and y-intercept Jeff Bivin -- LZHS

  3. y = 2x + 1 y = 2x + 1 Run 1 y-intercept Rise b = 1 2 slope m = 2 Jeff Bivin -- LZHS

  4. y = -3x + 2 y = -3x + 2 Run 1 y-intercept Rise b = 2 -3 slope m = -3 Jeff Bivin -- LZHS

  5. Run 3 y-intercept b = -1 Rise 2 slope Jeff Bivin -- LZHS

  6. Run 2 y-intercept Rise b = 3 -1 slope Jeff Bivin -- LZHS

  7. Graphing Lines x- and y- intercepts Jeff Bivin -- LZHS

  8. 2x + 3y = 5 find the x value when y = 0 x-intercept 2x + 3(0)= 5 2x + 0= 5 2x= 5 find the y value when x = 0 y-intercept 2(0) + 3y= 5 0 + 3y= 5 3y= 5 Jeff Bivin -- LZHS

  9. 4x - y = 6 find the x value when y = 0 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 Jeff Bivin -- LZHS

  10. 4x + 2y = 3 find the x value when y = 0 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 Jeff Bivin -- LZHS

  11. 3x - 2y = 7 find the x value when y = 0 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 Jeff Bivin -- LZHS
