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

(1,2)
(8,-54)
(5, -35)
(1,-7)

Option 2 - (8,-54)

Step-by-step explanation:

Given : Equation

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

Solution :

To check whether the given points is the solution substitute the the point in equation if they equate then it satisfied.

1) Point (1,2)

Not a solution.

2) Point (8,-54)

This is a solution.

3) Point (5,-35)

Not a solution.

3) Point (1,-7)

Not a solution.

Therefore, Option 2 is correct.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

15.36 per mile

but forgot to round

i am pretty sure
