Question

1. Which ordered pair is a solution of the equation y=4x?

(A). 1,3
(B). -1,-4
(C). -4,-1
(D). 1,-4

2. Which ordered pair is a solution of the equation y=-7x+2?

(A). 1,2
(B). 8,-52
(C). 5,-35
(D). 1,-7

PLEASE HELP‼️‼️

Answer 1

Substitute in the values and solve.

1) B

For A:

3 = 4(1)

This is NOT true.

For B:

-4 = 4(-1)

This IS true.

For C:

-1 = 4(-4)

This is NOT true.

For D:

-4 = 4(1)

This is NOT true.

2) None. Possible solutions: (0,2) (1,-5)

For A:

2 = -7(1) + 2

2 = -7 + 2

This is NOT true.

For B:

-52 = -7(8) + 2

-52 = -56 + 2

This is NOT true.

For C:

-35 = -7(5) + 2

-35 = -35 + 2

This is NOT true.

For D:

-7 = -7(1) + 2

-7 = -7 + 2

This is NOT true.

Answer 2

1) Option B is correct.

2) None option is correct.

Step-by-step explanation:

1) To find : Which ordered pair is a solution of the equation
`y=4x`?

Solution :

To check the ordered pair we have to substitute all points which satisfy the equation is the required point.

A) (1,3)

`3=4(1)`

`3\\eq 4`

Not true

B) (-1,-4)

`-4=4(-1)`

`-4= -4`

True

C) (-4,-1)

`-1=4(-4)`

`-1\\eq -16`

Not true.

D) (1,-4)

`-4=4(1)`

`-4\\eq 4`

Not true.

Therefore, Option B is correct.

2) To find : Which ordered pair is a solution of the equation
`y=-7x+2`?

Solution :

To check the ordered pair we have to substitute all points which satisfy the equation is the required point.

A) (1,2)

`2=-7(1)+2`

`2\\eq -5`

Not true

B) (8,-52)

`-52=-7(8)+2`

`-52\\eq -54`

Not true

C) (5,-35)

`-35=-7(5)+2`

`-35\\eq -33`

Not true.

D) (1,-7)

`-7=-7(1)+2`

`-7\\eq -5`

Not true.

Therefore, None option is correct.
