Answer:
Slope of the function is ,Y-intercept
.
The function is with initial value
,Jordan puts
each week andthe amount saved by Jordan after
week
.
Step-by-step explanation:
To understand the slope and y-intercept lets assign as number of weeks and
as the money saved by Jordan.
Jordan is already having a sum of inside the money bank so in
week the amount is
can be written as
in coordinate form.
SImilarly
We have and
Part A:
The function is
From point-slope form,we have slope (m)
and ,plugging the values of the points.
Y-intercept of this function is the constant term or the money of that is already inside the money bank.
We can also calculate y-intercept by arranging the function as choosing any
coordinate and here
is the y-intercept.
The result will be same.
Part B:
The equation <u></u> can represent the function described.
And the initial value is the <u>y-intercept </u>
Jordan puts<u> </u>in his bank each week.
After week the amount saved by Jordan ,here
,as the x-variable is the number of weeks.
Plugging the value of in
where
so the equation becomes
So basically the function is and the amount saved by Jordan after
week
.
