  2. Find the slope and the y-intercept of y = (3/2)x − 9. Write them like 2, -5.
  3. Find the slope and the y-intercept of y = −(1/2)x + 4. Write them like 2, -5.
  4. Find the slope and the y-intercept of y = (1/2)x − 6. Write them like 2, -5.
  5. Find the slope and the y-intercept of y = (3/2)x + 3. Write them like 2, -5.
  6. Find the slope and the y-intercept of y = (1/4)x + 11. Write them like 2, -5.
  7. Find the slope and the y-intercept of y = (1/2)x + 7. Write them like 2, -5.
  8. Find the slope and the y-intercept of y = (1/4)x + 12. Write them like 2, -5.
  9. Find the slope and the y-intercept of y = −(1/4)x − 4. Write them like 2, -5.
