what happens to a line when the y-intercept is changed

Question

i need to know the answer asap because i dnt want to fail plz

Answer 1

The y-intercept is the point where the line crosses the y-axis. If you change the y-intercept, that means that the line crosses the y-axis somewhere else. Depending on what remains constant, you may get different results. For example, if you don't change the slope, the entire line will simply move up or down.
