Which best compares the slopes and y-intercepts of the linear functions f and g, where f = 1/3x + 3 and g is shown in the table below?

 

x1234

g(x)36912

 

Is this part of a multiple choice question?

 

the gradient of f(x) is 1/3      the gradient of g(x) is 3         That is the positive reciprocal       f(x)=(x/3)+3

 

The y interecept of f(x) is 3    and the y intercept of g(x) is 0                                                  g(x)=3x

 

I sam not really sure what answer is being sort here.   

 

Here is what the graphs look like
