Graph the linear equation. Identify the x-intercept.

To graph the linear equation y = x - 4, we first need to find two points on the line. One easy point to find is the y-intercept, which occurs when x = 0.

When x = 0, y = 0 - 4 = -4. So, the y-intercept is at (0, -4).

Another point we can find is the x-intercept, which occurs when y = 0.

When y = 0, 0 = x - 4. Solving for x, we get x = 4. So, the x-intercept is at (4, 0).

Plot these two points on a graph and then draw a straight line passing through them.

The x-intercept is (4, 0).
