Question

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

Answer 1

the answer is

Explanation:

b

Answer 2

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
