Answer:
a=405
Step-by-step explanation:
 
        
             
        
        
        
A. Slope = 2
b. Slope = 2/3 or 0.66 
(Slope = change in y / change in x)
        
             
        
        
        
Step-by-step explanation:
Slope of line ST = Slope of line PQ = -3.
y = -3x + c
When x = 3, y = -1
=> (-1) = -3(3) + c, c = 8
Therefore the equation of line ST is y = -3x + 8 and the y-intercept is 8.
 
        
                    
             
        
        
        
Yes. Parallel means same slope as original line. So it’s 2
        
             
        
        
        
The equation for the table is y=2x+3.
