Question 1151266: Create a real-world scenario that is modelled by a linear relationship that:
Is partial variation
Has a negative rate of change

first recall:
is a relationship between two variables in which the dependent variable is the sum of a constant (NOT ZERO) and a constant multiple of the independent variable.
where is the initial value of or - intercept, and is a slope- the constant of variation (what increases by when increases by )
example:
A student is eating an ice cream cone at the park that is tall. It is extremely hot outside and the ice cream starts to melt at a constant rate of . If the student didn’t eat any of the ice cream and it started to melt, how much would be left after minutes?
1st: Identify the slope and - intercept
ice cream is melting , so (slope is negative because it is decreasing in size)
2nd: Plug into slope intercept form:
3rd: Plug in for since we want to know how tall it will be after minutes
4th: Solve
cm
Understand that after minutes of melting the ice cream cone will now measure .
