Look at the graph picture I attached

c is the intercept, which is why the graph crosses the y-axis at +3
to find where it crosses the x-axis, we make y = 0

 
        
             
        
        
        
9 is in parentheses therefore it's elevated above 3 that means you have to do operations on it first. 
3 + (-9) = -6
The sum is negative.

Answer:
   A. The equation represents a linear function because the equation is in the form y = mx + b
Step-by-step explanation:
A linear function does not have to be in the form y = mx + b, but if a function is in that form, it is a linear function.
   choice A is appropriate
__
A function may have two variables, x and y, and not be a linear function. For example, y = x² is not a linear function. The fact that it has two variables is not what makes it linear.
 
        
                    
             
        
        
        
No, you would only need to multiply 16 by 5 once
