Two quantities are related, as shown in the table:

x y
2 10
4 9
6 8
8 7

which equation best represents the relationship?
y = 1 over 2 x + 11
y = negative 1 over 2x + 11
y = 2x + 10
y = 2x + 11

It is y= -1/2 x +11

Use any two points on the data. In my case, I'll be using points (2,10) and (4,9) then find the slope. m= (9-10) / (4-2) = -1/2

Then use point slope form of a line.
y-10 = -1/2 (x-2)
y-10 = -1/2x +1
y= -1/2 x + 11

Where is the table?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
