(1,2)

(8,-54)

(5, -35)

(1,-7)

Verified Answer :

answer
(8,-54)

,,,,,,,,,,,,,,,,,,,,,,,,

when x = 8 then

y = -7(8) + 2
y = -56 + 2
y = -54

Answer:

Option 2 - (8,-54)

Step-by-step explanation:

Given : Equation \(y=-7x+2\)

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)

\(y=-7x+2\)

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

\(2=-7+2\)

\(2 eq-5\)

Not a solution.

2) Point (8,-54)

\(y=-7x+2\)

\(-54=-7(8)+2\)

\(-54=-56+2\)

\(-54=-54\)

This is a solution.

3) Point (5,-35)

\(y=-7x+2\)

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

\(-35=-35+2\)

\(-35 eq-33\)

Not a solution.

3) Point (1,-7)

\(y=-7x+2\)

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

\(-7=-7+2\)

\(-7 eq-5\)

Not a solution.

Therefore, Option 2 is correct.
