Question

Function A is represented by the equation y = 6x - 1.

Answer 1

Answer:

The function graphed is f(x) = 3x + 1

See that the y=intercept is at (0,1). That's where the +1 comes from.  

Note that the graph goes up 3 spaces every time it goes 1 to the right.  3/1 = 3 is the slope.

The answer to 12 is C.

The answer to 13 is B.  Neither is a function.  For a function of x to exist, for every x, there must be only one y.  In both tables, there's a number for x that gives two different y's.
