Answer:

slope = - 50

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, 2400) and (x₂, y₂ ) = (12, 2000) ← 2 points on the line

m = \frac{2000-2400}{12-4} = \frac{-400}{8} = - 50

AnnZ [28]

Answer:

Capital: 2 400

Tasa: 5% = 5/100 = 1/20

Tiempo: 4 años

A) Interés = capital*tasa*tiempo

Interés = 2400*(1/20)*4

Interés = 480 soles

B) Interés = Capital*((1 + tasa)^tiempo+1)

Interés = 2400*((1 + 1/20)^4 + 1)

Interés = 2400*((21/20)^4 + 1)

Interés = 2400*(194 481/160 000 + 1)

Interés = 2400*(354 481/160 000)
