Question

select a ordered pair that is a solution of this equation.
-2x+6y=-4

Answer 1

You could select any value for either x or y and evaluate the other one. I'll use x=1

-2(1)+6y=-4
-2+6y=-4
6y=-2
y=-2/6
y=-1/3

Answer 2

are there choices?

Answer 3

If you don't want fractions, you might have to experiment a bit to find integers.

Answer 4

Like Mathdrills said that's one ordered pair, I could use x=0 and get another one. Actually using x=4 might give u nicer numbers

Answer 5

yes i have choices (-3,-7) (-7,-3) (-7,6)

Answer 6

okay so try each of those out. For which of these is the equation above true?

Answer 7

That basically means:
Is: -2(-2)+6(-7)=-4

Answer 8

Is: -2(-7)+6(-3)=-4

Answer 9

Is: -2(-7)*6(6)=-4?

Answer 10

Do the multiplication/addition and show me which one is true.

Answer 11

i dont understand ;/ what will the answer be?

Answer 12

Okay this is what it means. An ordered pair must be the solution to that equation.
Your choices are: (-3,-7) (-7,-3) (-7,6), or they can also be written as:
1) x=-3; y=-7
2) x=-7; y=-3
3) x=-7; y=6

Answer 13

Plug each of those into the equation:
1) -2x+6y=-4;
-2(-3)+6(-7) = -4

Answer 14

Now tell me is this true:
-2(-3)+6(-7) = -4 ?

Answer 15

no ;[

Answer 16

You are right. Moving on to the next point:
2) -2x+6y=-4;
-2(-7)+6(-3) = -4; is this one true?
