Step-by-step explanation:
The x-intercepts are the points in which the line crosses the x-axis. Another word for this are the zeroes, because y=0 would be right on the x-axis, and finding the zeroes would be finding the points that cross y=0. Notice how the points listen on the answer are right on the x-axis of each graph; they intercept the x-axis.
