Rage, this is the solution:
1. The x-intercept is (4, 0) False, this function does not cross the x-axis.
2. It has a slope of zero. Correct. The function is constant.
3. The graph would be a vertical line. False, the graph actually is a horizontal line.
4. The point (4, 2) is on the line. False. The point (2, 4) is on the line.
