Question

Which of the following points are NOT on the graph of y = -2x + 3?

Answer 1

What are the options?

Answer 2

1,1
-1,5
-2,3
2,-1

Answer 3

It's -2,3. It took me a while to read the graph coordinates, but there's no -2,3

Answer 4

thanks zeinas !

Answer 5

You're welcome.

Answer 6

Which of the following points are NOT on the graph of y = -4x + 4?
1,0
2,4
0,4
-1,8

Answer 7

(2,4). It's completely off the graph. And one way that you can do this is to put the points in the equation, and the one that doesn't make it equal to each other is wrong.

Answer 8

Which of the following points are NOT on the graph of y = x + 2?
-1,1
1,3
3,5
5,9
My answer was 5,9 ?

Answer 9

That's right :D

Answer 10

this one confused me a little bit
my answer was 9,7
The answers are
9,7
-3,-1
-6,-3
6,3

Answer 11

What's the equation for the graph?

Answer 12

\[y=\frac{ 2 }{ 3 }x+1\]

Answer 13

Well it could not be 9,7 because
7=2/3(9)+1
7=6+1
7=7
But when you try the last point (6,3) we get
3=2/3(6)+1
3=4+1
3=5
and that is wrong so its d.

Answer 14

thanks (: what about the y=x^2-1
0, -1
1, 0
-1, 0
0, 0
is it C ?

Answer 15

0=(-1)^2-1
0=1-1
0=0 so it fits
But D is
0=(0)^2-1
0=-1
It's D because it doesn't fit.

Answer 16

thanks.Which of the following points are NOT on the graph of y = 2x?
-2, 0
2, 4
4, 8
0, 0

Answer 17

It's a.
0=2(-2)
0=-4

Answer 18

thank you (:

Answer 19

No problem. :)
