Question

Which ordered pair is a solution of the equation?

Answer 1

Answer
(8,-54)

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

when x = 8 then

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

Answer 2

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)

$y=-7x+2$

$2=-7(1)+2$

$2=-7+2$

$2\neq-5$

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)

$y=-7x+2$

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

$-35=-35+2$

$-35\neq-33$

Not a solution.

3) Point (1,-7)

$y=-7x+2$

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

$-7=-7+2$

$-7\neq-5$

Not a solution.

Therefore, Option 2 is correct.
