Answer 1

Hey, my name is Hannah too! :) Anyways, what options of sets of ordered pairs were given?

Answer 2

if 3+3=9 the i believe the answer is B

Answer 3

{(-15, -21), (-6, -12), (-1, -7)}
{(-15, 21), (-6, 12), (-1, 7)}
{(-15, 21), (-6, 12), (-1, -7)}
Theses are the answer choices.

Answer 4

well hannah all you need do is substitute for the 3 values of x in the equation to find values of y

Answer 5

Yeah, what welshfella said...

Answer 6

for example
put x = -15 into a + y = 6

-15 + y = 6
add 15 to both sides
y = 6 +15 = 21

so we know that either b or c are the correct options as a has (-15,-21)

so next try x = -6

Answer 7

so is it b or c?

Answer 8

yes - to find out which try plugging in the next value of x which is -6 and see what you get

Answer 9

all you have to do is replace the x in x + y = 6 with -6 and work out what y is

Answer 10

uhm... is still don't understand, but ok.

Answer 11

-1 + y = 6

now solve for y

Answer 12

y=7

Answer 13

yeah = thats the third value - butthats ok
now you should be able to choose the correct option
b or c?

Answer 14

find the one containing ( -1,7)

Answer 15

Butthats? whats that even mean... and b

Answer 16

lol but that's
