Help please ;-; The values in the table represent a linear function.
Fittoniya [83]

Answer:

The function rule in slope-intercept form is:

y = \frac{1}{2}x-\frac{7}{2}

Step-by-step explanation:

The slope-intercept form of a function is given as:

y = mx+b

Here

m is the rate of change of function and b is the y-intercept

The rate of change is calculated as:

m = \frac{difference\ in\ y}{difference\ in\ x}

For this, any two pairs of input and output can be taken.

So using the pairs (1,-3) and (2,-1)

m=\frac{2-1}{-1+3}\\=\frac{1}{2}

Putting the value of slope in slope-intercept form

y = \frac{1}{2}x+b

Putting (1,-3) in the equation

-3 = \frac{1}{2}(1)+b\\-3 = \frac{1}{2}+b\\b = -3-\frac{1}{2}\\b = \frac{-6-1}{2}\\b= \frac{-7}{2}

Putting the value of b

y = \frac{1}{2}x-\frac{7}{2}

Hence,

The function rule in slope-intercept form is:

y = \frac{1}{2}x-\frac{7}{2}

Peter deposited $8,975 into a savings account 21 years ago. The account has an interest rate of 3.8% and the balance is currentl
Alexus [3.1K]
The formula for the future value of the account is
  A = P(1 + r/n)^(nt)
where you have
  A = 19909.20
  P = 8975
  r = 0.038
  t = 21

The resulting equation is not one that can be solved by algebraic means, but we can use a graphing calculator to find n. This graph shows us n = 12, so

the interest compounds monthly.
