Final answer:
To find the x-intercept of a linear function, set the y-coordinate to zero and solve for x. The x-intercept occurs when y = 0.
Step-by-step explanation:
The x-intercept of a linear function represents the point where the graph of the function crosses the x-axis. To find the x-intercept, set the y-coordinate to zero and solve for x. In the equation, y = mx + b, the x-intercept occurs when y = 0. Set y = 0 and solve for x to find the x-intercept.
For example, if the linear function is y = 2x - 1, set y = 0 and solve for x:
- 0 = 2x - 1
- 2x = 1
- x = 1/2
Therefore, the x-intercept of the linear function y = 2x - 1 is (1/2, 0).
