What equation is represented by the equation on the graph?

a) y= - 1/2 x-2
b) y= - x - 2
c) y= - 1/2 x + 2
d) y= - x + 2

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

If f(x)= sqrt4x+9+2, which inequality can be used to find the domain of f(x)?
