@72595210002 : You simply need to check each pair and see which option provides you with all 3 pairs where the y value is the x-value with 7 added to it.

i did not get it

shiraz14 · Answer

Example for option A: for the first coordinate pair (0, 7), x=0 & y=7. Since y=x+7, this would satisfy the criteria in the question. Do this with all the other coordinate pairs and find the correct option. Can you post your answer in this thread when you have done this?

i guess C

shiraz14 · Answer

For C, the first coordinate pair is (1, 7). x=1 & y=7. Does this satisfy the criteria in the question (i.e. y=x+7)?

anonymous · Answer

Plug in the ordered pairs (x,y) and check to see if they match the solution

anonymous · Answer

it is B
