Question

I'm stuck.... help?

Answer 1

Any guess ??

Answer 2

No... I did the best that I could

Answer 3

repitation is coming in it

Answer 4

If any point is on x axis then its y co ordinate is always zero
If any point is on y axis then its x co ordinate is always zero getting ???

Answer 5

C is point on quadrant II

Answer 6

for the last question
y= -x + 1

you can test each pair: replace the "x" with the first number from the pair.
simplify and see if you get the second number. If you do, you found the answer

Answer 7

you are not right for option c

Answer 8

you can do the something for
2x -3y= -6
replace both the x (with the first number of the pair), and the y (from the second number)
simplify. If you get -6, you found the correct pair.

Answer 9

2x-3y=-6 is (-6, 3)

Answer 10

let's see: 2*-6 - 3*3 = -12-9 = -21
but you want -6.

Answer 11

please check this

Answer 12

Then it's not (-6, 7) either

Answer 13

you just have to grit your teeth and test each pair.

Answer 14

2*-6 - 3*7= -12-21=33

Answer 15

That's not the answer.

Answer 16

try (3,4)

Answer 17

btw you meant 2*-6 - 3*7= -12-21= -33

Answer 18

That does equal -6...

Answer 19

Wow, that was easy

Answer 20

can you do the last question
y = -x + 1

Answer 21

How would I solve for y=-x+1?

Answer 22

replace x and y with the first number and second number of a pair
simplify the right side, and see if you get the same number on both sides.

test the pairs that are not already an answer for the other questions

Answer 23

So I have (-6, 3) and (-6, 7) left...

Answer 24

3=-6+1 = 3=-5
7=-6+1 = 7=-5

Answer 25

you have to be careful about the signs

y = -x + 1
try (-6,3)
(notice x is -6)
y = - (-6) + 1
y = 6+1
y=7

it looks like if x= -6 you get y= 7

Answer 26

so (-6,7) is the answer

Answer 27

oh, i didn't put the - in parenthesis

Answer 28

I put the parens in to make it more clear.
but you could write it
7 = - -6 + 1
and get
7= 6+1
7=7

the important thing is to not confuse
y = -x + 1
and
y = x + 1
