Final answer:
The x-intercept of the line y = ½x - 3 is found by setting y to 0 and solving for x, which results in an x-intercept of 6.
Step-by-step explanation:
The x-intercept of a line is the point where the line crosses the x-axis, which is when the value of y is 0. Given the equation y = ½x - 3, we can find the x-intercept by setting y to 0 and solving for x:
- Set y equal to 0: 0 = ½x - 3.
- Multiply both sides by 2 to eliminate the fraction: 0 = x - 6.
- Add 6 to both sides of the equation: x = 6.
Therefore, the x-intercept of the line is 6, which corresponds to option 2).
