Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (4, - 5) and (x₂, y₂ ) = (- 2, 1)

m = \frac{1+5}{-2-4} = \frac{6}{-6} = - 1

Anya's grandparents decide they want to invest at the bank. They have $35,000
Aneli [31]

Anya's parents will have $44,440.71 after 6 years if they invested in a bank.

The interest rate given is an annual rate yet will be compounded quarterly. You therefore need to convert the interest rate to a quarterly rate.

= 4% / 4 quarters

= 1% per quarter

Number of periods:

= Number of years x Number of quarters in year

= 6 x 4

= 24 quarters

The amount they will have in their account is:

<em>= Amount x ( 1 + rate) ^ number of periods </em>

= 35,000 x ( 1 + 1%)²⁴

= $44,440.71

In conclusion, they will have $44,440.71 if they invested their money in a bank for 6 years.

Answer:

f(0) = -3

x increases by 1 f(x) increase by 2

f(x) = 2x -3

Step-by-step explanation:

Looking at the graph

f(0) means when x =0 the value of y = ?

when x = 0 y = -3

f(1) means when x = 1  y = ?

When x = 1 y = -1

y increased from -3 to -1 so it increased by 2

f(x) = ax+b  where a is the increase and b is the value at x =0

f(x) = 2x -3
