1.(2,6)
2.(6,2)
3.(-2,6)
4.(-6,2)

Answer 1

What's your question?

Answer 2

the question is what is y=x-4

Answer 3

Answer 4

that's all it asks?

Answer 5

it seems odd they also list a bunch of points

Answer 6

yes that's basically it

Answer 7

are they asking anything like if they are solutions to the equation?

Answer 8

yes they are asking if any of those ordered pairs are the solution to y=x-4

Answer 9

Let's test (2,6)

Answer 10

what is x and y if we have the point (2,6) ?

Answer 11

x=2 and y=6

Answer 12

y=x-4

y=2-4 ... replace x with 2 (since x = 2)

6 = 2-4 ... replace y with 6 (since y = 6)

6 = -2 ... this equation is FALSE

Answer 13

ok so whats next?

Answer 14

since plugging in (x,y) = (2,6) into y=x-4 leads to a false equation, this means (2,6) is NOT a solution to y=x-4

visually, the point (2,6) is NOT on the line y=x-4

Answer 15

how about (-2,6)

Answer 16

plug (x,y)=(-2,6) into y=x-4 and tell me what you get

Answer 17

I actually did (-6,2)
y=x-4
2=-6-4
2=2

Answer 18

-6-4 is not equal to 2

Answer 19

-6-4 is equal to -10

Answer 20

so

2 = -6-4

2 = -10

which is false, so (-6,2) is not a solution to y = x-4
