Answer:
A y-intercept is the point on a graph where the line crosses the y-axis. For example, a y-intercept of 5 would mean that the line crosses the y-axis at the coordinates (0, 5).
An x-intercept is then pretty self explanatory. It is the point on a graph where the line crosses the x-axis. For example, an x-intercept of 3 would mean that the line crosses the x-axis at the coordinates (3,0).
Hope this helps you understand! :)
