Respuesta :

Answer:

B

Step-by-step explanation:

Given

5x + y = 14 ( subtract 5x from both sides )

y = 14 - 5x

Substituting values of x into the right side allows the corresponding value of y to be found.

x = - 1 : y = 14 - 5( - 1) = 14 + 5 = 19

x = 0 : y = 14 - 5(0) = 14 - 0 = 14

x = 1 : y = 14 - 5(1) = 14 - 5 = 9

Hence the corresponding values of x and y are

x    y

- 1   19

0     14

1       9
