Question

What is the function rule for the graph shown?

Answer 1

y = x – 8

 y = x + 8

 y = 8x

 

Answer 2

the last one is y equals 1 over 8 X

Answer 3

Plug in the value of x in each equation and see which one checks.
For example let's take the first point (8.0) :
y = 8 - 8
y = 8 + 8
y = 1/8*8
So which one checks in your opinion ?

Answer 4

Y=x-8

Answer 5

Yep !
