Answer:
1) -100
2) Your laptop would lose value faster
3) Your laptop would lose value slower
4) Your laptop's value increases as time goes on
5) It is a horizontal line
6) the laptop's value doesn't change over time
7) A vertical line
Step-by-step explanation:
1) the slope of the line is -100. You can figure this out by doing rise/run
2) If the line were steeper, the laptop would lose more value each year, meaning that the laptop would lose it's value faster
3) If the line were less steep, the laptop would lose less value over each year, so it's value would decrease slower.
4) If the slope was positive, that means that the laptop would be gaining value as the time increases or goes by
5) A slope of zero has a rise over run of 0/something, meaning that the rise or change in y should be equal to zero. This can only occur in a horizontal line.
6) If the y-value doesn't change, that means that the value isn't changing as time goes by.
7) A line with an undefined slope has a rise over run of something/0 and it's undefined because anything divided by 0 is undefined. In this situation, the run, or change in x is 0, and this can only occur in a vertical line
