If the graph of the function 
is a line with slope 
, which of the following could be the equation of 
?
(A)
(B)
(C)
(D)
(E) 
The Correct answer is B.
Explanation
The graphs of all the given functions are lines, and the equations are all in the form 
. When a linear equation is in the form 
, the slope of the graph of the equation is 
, the coefficient of 
. The graph of the function 
is a line with slope 
, so the only choice that could be the equation of 
is 
.
