Writing a real-world situation modeled after an equation / graph

[mighty harness]

I'm blanking on ideas, can someone help?

[ocean kestrel]

Like the equation of the line

Or a real world situation involving it

[mighty harness]

I have an example of one sorta but it's not the same format, I think it's a different type of equation tho. it's point slope form and not slope intercept form

I'm using y=mx+b for the question I'm doing rn tho

[ocean kestrel]

you could say something about a bank scenario

like

Someone deposits $100 in a bank

and puts $15 every week after that

[mighty harness]

so the 100 would represent what and the 15 $ would represent like money added to savings per week?

[ocean kestrel]

the 100 would be y - intercept

because the account opens after your deposit

so you would have 100 after "0" weeks

which is modeled by your graph

[mighty harness]

basically the down payment

okay okay

[ocean kestrel]

so on x axis would be time (weeks)

and y - axis would be total amount of money

($)

[mighty harness]

would there need to be an end result or something like that?

[ocean kestrel]

i mean all the situation needs to do is keep a linear constant and match up with the graph

[mighty harness]

I have
Oli decided to open up a bank account. He deposited $100 for the first investment. Every week, he deposites $15 into the account.

anything you would change?

[ocean kestrel]

every week after that

makes it more clear

[mighty harness]

okay that makes sense, thank you!!
