Answer:

y equals three sevenths times x plus 3

Step-by-step explanation:

Given the information:

  • points going up from about zero comma negative 3

<=> Let A (x1, y1) =  (0, -3)

  • to the right to about 7 comma zero

<=> Let B (x2, y2) = (7, 0)

As we know, the line of best fit is a linear equation that represent the data with the standard form:

y = mx + b where:

  • m is the slope
  • b is the the y-intercept when x = 0

For a line that goes trough the points (x1, y1) and (x2, y2), the slope is

m = \frac{y2-y1}{x2-x1}

In this situation, we have:

m = \frac{0-(-3)}{7-0} = \frac{3}{7}  

=> y = \frac{-3}{7}  x + b.

Because the line goes through A (0, 3)

=> 3 = \frac{3}{7}  *0 + b

<=> b =3

=> y = \frac{3}{7}  x +  3

So we choose y equals three sevenths times x plus 3

Answer:

La cantidad de dinero adeuda al final de los dos procesos es $1450

Step-by-step explanation:

Los parámetros del proceso son;

La cantidad ahorrada para comprar ropa = $2,000

La cantidad pagada por la ropa = $2600

La cantidad prestada a un amigo = $650

La cantidad adeuda por teléfono celular durante 3 meses = $250

Deje que 'C', represente la suma de las transacciones anteriores, tenemos;

∴ C = 2,000 - 2,600 - 650 - 200 = -1,450

La suma de las transacciones anteriores, C = -$1,450

Por lo tanto, al final de los dos procesos, la cantidad de dinero adeuda es C = $1,450
