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 ‼️‼️

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 ?

Solution :

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

A) (1,3)

Not true

B) (-1,-4)

True

C) (-4,-1)

Not true.

D) (1,-4)

Not true.

Therefore, Option B is correct.

2) To find : Which ordered pair is a solution of the equation ?

Solution :

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

A) (1,2)

Not true

B) (8,-52)

Not true

C) (5,-35)

Not true.

D) (1,-7)

Not true.

Therefore, None option is correct.

you meant circumference well the answer is:

17.27876 miles

area is 23.7583

the radius is 2.75 miles

hope this hmu if needed.
