Y=1/2x +0. You add the 2x to the other side, and then divide everything by 4 to have only 1y.
Hey can you take another pic
Answer:
Domain is the set of inputs that will give you a defined output.
In example, f(x)=5/x, the domain would be all real numbers except for 0, because if it would be 0, it would be 5/0 which would be undefined.
Range is the set of outputs that are possible.
In example, f(g)=g(0), the range would be 0.
Answer:

Step-by-step explanation:
directly means y = kx where k is a constant. you have to first find the constant.
now you have your equation 
so you simply plug in x and find y
