Which of the following is a solution to the linear function 2x - y = - 1

(2, - 1)

(1, 2)

(-3, - 1)

(1, 3)

The solution to this equation is (1, 3)

Step-by-step explanation:

In order to determine if it is a solution, you must put both variables into the equation and have it produce a true statement. (1, 3) does exactly that.

2x - y = - 1

2 (1) - (3) = - 1

2 - 3 = - 1

-1 = - 1 (TRUE)
