Question

Which ordered pair is a solution to the equation y = 6x - 4? The answer choices are A) (2, 1)

Answer 1

Answer:

Solution for the equations are y = 6x - 4 are (1, 2) .

Option (B) is correct .

Step-by-step explanation:

Solution of a equation

 Values which when substituted for a variable in an equation, make the equation true.

As given the expression in the questions are

y = 6x - 4

First part

Take (2, 1) points .

x = 2 , y = 1

Put these values of x and y in the equation

1 = 6 × 2 - 4

1 = 12 - 4

1 ≠ 8

(2, 1)  are not the solution of the equation  y = 6x - 4 .

Second part

Take (1,2) points

x = 1 , y = 2

Put these values of x and y in the equation  y = 6x - 4 .

2 = 6 × 1 - 4

2 + 4 = 6

6 = 6

(1, 2) satisfied the equation y = 6x - 4 .

Third part

Take (2, 6) points .

x = 2 , y = 6

6 = 6 × 2 - 4

6 = 12 - 4

6 ≠ 8

Thus (2, 6) are not the solution of the equation   y = 6x - 4 .

Fourth part

Take (1, 1) point

x = 1 , y = 1

1 = 6 × 1 - 4

1 ≠ 2

Thus (1, 1) is not  the solution of the equation   y = 6x - 4 .

Therefore  Solution for the equations are y = 6x - 4 are (1, 2) .

Option (B) is correct .

Answer 2

B

Substitute the first number for x and see which one it is

6 x 1 - 4 = 2
