Question

Determine which ordered pair is not a solution of y = –5x – 4, Explain?
(10, –52)
(7, –39)
(–7, 31)
(8, –44)

Answer 1

Plug in the x value and y value

Start with A

x = 10 , y = -52

-52 = -5 * 10 - 4

Does this come out as true?

Answer 2

No, That would be -54, Right?

Answer 3

Right so it is `NOT` a solution.

Answer 4

Okay, So A is out of the question now

Answer 5

The question said to look for the ordered pair that is `not` the solution. :P

Answer 6

Oh, My bad. >_<, Sorry. Really stressed out with this end of year work

Answer 7

Thank you for your help. ^_^!

Answer 8

You can check with B, C, and D

-39 = -5 * 7 - 4

31 = -5 * - 7 - 4

-44 = -5 * 8 - 4

It's ok :) and you're welcome ^_^
