Which ordered pair is the best estimate for the solution of the system of equations? y=−2/5x−2y=5x+1

(−0.5, −1.75)

(−1, −2)

(0, −2)

(−0.5, −1)

Option a: is the solution to the system of equations.

Explanation:

The equations are and

Equating these two equations, we have,

Taking LCM and multiplying both sides by 5, we get,

Simplifying , we get,

Substituting the value of x in , we get,

Thus, the solution is

Changing the solution from fraction to decimal, we get,

Thus, the solution is

Hence, option a is the correct answer.
