Question

Which ordered pair satisfy the equation y =2x.

​

Answer 1

Answer:

(2,4) (3,6) (4,8) etc.

Step-by-step explanation:

As you know, there are many, in fact, infinite answers for a linear equation in 2 variable.

Answer 2

Answer:

(- 1, - 2), (0, 0), (1, 2), (2, 4), (3, 6).

Step-by-step explanation:

An ordered pair is in the form of ( x, y ) that describes a particular location in a coordinate plane where, the first number represents x axis and second represents y axis.

Using the equation y = 2x, some ordered pairs are as follows (- 1, - 2), (0, 0), (1, 2), (2, 4), (3, 6).

Let us find the ordered pairs that satisfies the above equation.

Given that y = 2x

Let's take different values of x and substitute in the given equation to get the values of y.

⇒ y = 2 ( -1) = - 2

⇒ y = 2 ( 0 ) = 0

⇒ y = 2 ( 1 ) = 2

⇒ y = 2 ( 2 ) = 4

⇒ y = 2 ( 3 ) = 6

From the above equation, the ordered pairs we get are (- 1, - 2), (0, 0), (1, 2), (2, 4), (3, 6).
