Worked examples
Two examples
Example 1
What is the x-intercept of 2x + 3y = 12?
- On the x-axis, y = 0: 2x = 12.
- x = 6. The line crosses the x-axis at (6, 0).
Answer: 6
Example 2
What is the y-intercept of 2x + 3y = 12?
- On the y-axis, x = 0: 3y = 12.
- y = 4. The line crosses the y-axis at (0, 4).
Answer: 4
