Year 9 maths · Fieldbook Learning

Name ______________________ Date __________

In y = mx + b, m is the slope and b is the y-intercept. For the x-intercept, set y = 0 and solve for x.

  1. What is the slope of the line y = (1/3)x − 8?
  2. What is the slope of the line y = −(5/2)x − 3?
  3. What is the slope of the line y = (5/2)x + 5?
  4. What is the slope of the line y = (2/3)x − 4?
  5. What is the slope of the line y = −(1/4)x − 9?
  6. What is the slope of the line y = −(1/3)x + 10?
  7. What is the slope of the line y = (7/3)x − 10?
  8. What is the slope of the line y = −(1/2)x − 3?
  9. What is the slope of the line y = −(9/4)x − 12?
  10. What is the slope of the line y = (4/5)x + 11?
  11. What is the slope of the line y = −(1/2)x + 5?
