wikiHow Practice Problems to Find the Y Intercept 1. y = 2x + 4 2. y = -3x + 6 3. y = x + 3 4. y = -x + 5 5. y = 1/2x + 7 6. y = -1/2x + 8 7. y = 3x + 2 8. y = -2x + 10 9. y = 4x - 3 10. y = -5x + 9 11. A line has a slope of 2 and passes through the point (0, 4). What is the y-intercept of the line? 12. A line passes through the point (3, 5) and has a slope of -1. What is the y-intercept of the line? 13. A line with a slope of 3/2 intersects the y-axis at a point with a y-coordinate of 7. What is the y-intercept of the line? 14. A line with a slope of -2 intersects the y-axis at a point with a y-coordinate of 6. What is the y-intercept of the line? 15. A line with a slope of 1 passes through the point (-2, 5). What is the y-intercept of the line? 16. A line with a slope of -3/2 intersects the y-axis at a point with a y-coordinate of 9. What is the y-intercept of the line? 17. A line with a slope of 4 passes through the point (1, 2). What is the y-intercept of the line? 18. A line with a slope of -1/2 intersects the y-axis at a point with a y-coordinate of 8. What is the y-intercept of the line? 19. A line passes through the point (0, 10) and has a slope of 3. What is the y-intercept of the line? 20. A line with a slope of -5 passes through the point (2, 4). What is the y-intercept of the line? Answer key: 1. y-intercept = 4 2. y-intercept = 6 3. y-intercept = 3 4. y-intercept = 5 5. y-intercept = 7 6. y-intercept = 8 7. y-intercept = 2 8. y-intercept = 10 9. y-intercept = -3 10. y-intercept = 9 11. y-intercept = 4 12. y-intercept = 2 13. y-intercept = 7 14. y-intercept = 6 15. y-intercept = 7 16. y-intercept = 9 17. y-intercept = -2 18. y-intercept = 8 19. y-intercept = 10 20. y-intercept = -3 Page
