Question

Which shows three ordered pairs that are all solutions of the equation y = x + 7?

A.
(0, 7), (2, 9), and (3, 11)

B.
(0, 7), (2, 9), and (3, 10)

C.
(1, 7), (2, 9), and (3, 10)

D.
(1, 8), (2, 9), and (3, 11)

Answer 1

Just substitute in the options for x and y :)

Answer 2

plug all the coordinates for each option into the equation and see if the equation holds true

Answer 3

what

Answer 4

Let me explain. In the first coordinate of the first option, 0 is x and 7 is y. So, if you substitute those in, you get 7 = 0 + 7

Answer 5

ex.
A) (0,7) >>>> 7=0+7 >>> 7=7 << correct
now do that for all the coordinates

Answer 6

@sleepyjess keeps on beating me.....

Answer 7

so its a

Answer 8

Which is true, now can you try for the coordinate 2, 9?

Answer 9

no i am just giving an example

Answer 10

No, both A and B have the coordinate 0, 7. So we need to test the others.

Answer 11

still dont get it

Answer 12

hmmmm... what don't you understand?

Answer 13

everything

Answer 14

ok, do you understand what a coordinate is?

Answer 15

a little

Answer 16

i think its b

Answer 17

A coordinate is an x and y value, in the order x, y. For example, in two of the options, there is the coordinate 0, 7. 0 is x, and 7 is y.

Answer 18

oh ok

Answer 19

Do you understand that so far?

Answer 20
