Standard Form

Write the equation of a line in Standard Form if given the following information. Then graph the equation using the slope-intercept form of the lines.

  1. m = 3/4 (5, 7)
  2. m = - 2/3 (- 10, 4)
  3. m = 7/5 ( - 2, 6)
  4. m = 5/6 (- 10, 11)
  5. m = - 3/8 (- 4, 5)
  6. m = - 1/7 (6, 8)
  7. (10, 7) (18, 4)
  8. (15, - 12) (2, - 5)
  9. (- 3, - 4) (- 15, 6)
  10. (2, 7) (- 8, 3)

Here are the answers to the HW problems:
1. 3x – 4y = - 13
2. 2x + 3y = - 8
3. 7x – 5y = - 44
4. 5x – 6y = - 116
5. 3x + 8y = 28
6. x + 7y = 62
7. 3x + 8y = 86
8. 7x + 3y = - 1
9. 5x + 6y = - 39
10. 2x – 5y = -31
