  1. Graphing Equations using Intercepts

  2. 3x - 8y = -24 Is the point (-8,0) a solution to this equation? What are two ways to prove that it is or isn’t? 1)It’s a point on the line! 2)

  3. 3x - 8y = -24 (-8,0) is also known as the x-intercept of the equation.

  4. Identify the ordered pairs for the x-intercept of each line (-2,0) (-4,0) (2,0) (7,0)

  5. (2,0) (-4,0) (-2,0) (7,0) What do the four ordered pairs have in common? y-value 0 All x-intercepts have a __________ of ___

  6. How do find the x-intercept if you don’t have the graph? y-value 0 All x-intercepts have a __________ of ___ !!! 0 (-7,0)

  7. b) Find the x-intercept for each equation (-4,0) (-5,0) a)

  8. 3x - 8y = -24 (0,3) is also known as the y-intercept of the equation.

  9. Identify the ordered pairs for the y-intercept of each line (0,-3) (0,3) (0,-5) (0,8)

  10. (0,3) (0,-3) (0,-5) (0,8) What do the four ordered pairs have in common? x-value 0 All y-intercepts have a __________ of ___

  11. How do find the y-intercept if you don’t have the graph? x-value 0 All y-intercepts have a __________ of ___ !!! 0 (0,2) y

  12. b) Find the y-intercept for each equation y y (0,4) (0,6) a)

  13. Graphing using the x and y intercepts x-intercept y-intercept
