Answer:
Part 1) 
Part 2) The graph in the attached figure
Step-by-step explanation:
Part 1)
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have

substitute in the linear equation

solve for b

substitute

Part 2) Draw the equation
we know that
To graph a line we need two points
we have the y-intercept (0,4) and (2,-4)
Plot the points, connect them and join to draw the line
see the attached figure
 
        
             
        
        
        
Answer:
The function would be 
.This is in the general form 
, where a is the initial value, b is the rate it increases by, and x is the amount of time.  For our function, the initial value is 4 and the rate it increases by is 2.
