Slope and intercept meaning in context

Practice determining which feature of a linear model (the slope, the x-intercept, or the y-intercept) is useful for answering a given question in context.

Want to join the conversation?

• is slope run over rise or rise over run
• it is rise over run
• So I understand both lessons, but I can't seem to understand the first practice (Relating linear contexts to graph features), the second one is very clear to me (Using slope and intercepts in context). Could someone explain it so I can better understand it?
• **********************************Hard Question**********************************
What if John loaned Flynn 28 dollars? And Flynn's salary per week is 3 dollars. And every week the loan increases by 0.078 percent until Flynn paid every single dollar. How long will it take for Flynn to pay John back? And how much will it cost him at last?

• Rise over run
• Did Flynn have to pay interest? Just kidding :)
• Hello, this video makes sense, but the assignment has nothing to do with this, I can't figure out what the heck the assignment even is talking about. The assignment is: Relating linear contexts to graph features
• NOTE: i'm trying to reach some new badges, can you guys pls give this answer some upvotes? thx
btw im tryna reach 50+ upvotes

the assigment does have to do with the video, the assignment is asking you to find a relationship in the points. If you see how the x goes to the next number and how the y goes to the next number, you can see a pattern. The pattern is that whenever x changes by a specific value, y has to change by a specific value too. You should try to use the pattern until x or y reaches 0, then you will find the x or y intercept. Hope this helped!!
• Could a payment plan that had interest be plotted with a line?
• Yes, as long as it isn't compound interest (which is a curve).

If you had a loan (l) of \$1000 with a simple 10% interest rate (i) being paid back in 12 monthly payments (p), you would use the following equation to get the total \$ amount due:
l + l(i * p)
Which with the above information would be:
\$1000 + \$1000(0.10 * 12) = 2200
From here you can simply graph a line with x being monthly payments made, and y being the remaining debt.

I hope this helps!
• what is a intersept and what does it do.

• Intercept is the point where the function touches the x-axis or y-axis.

For example, if you have a function modelling time of studying versus the result. Time should be the x-axis, and result should be the y-axis. You want to know when a person didn't study, what is their result. When a person didn't study, it means the time = 0, which is the y-intercept.
• He used the most easiest examples possible the practice test is way more complex than this.

• Examples are meant to help you understand the topic, and not demonstrating all possible cases.

You're expected to understand this topic, and solve the practice using your own knowledge.
