Question 180809
EASY WAY!!!!!!!!!!!!!! NEED TO REMEMBER ONLY ONE FORMULA 
                        
let see what i know xy=(5,-3) Slope = -3 FROM y = -3x + 9 PARALLEL EQUATION 
                        
ALWAYS HAVE SAME SLOPE(M)
                        
take the x=5 and y= -3 that is given and also we know the slope(M)= -3

y = mx + b
y = -3x + b
-3 = -3(5) + b
-3 = -15 + b
+15  +15
------------
12 = b

lets take the same formula again Y = mx + b and plug in slope(M) and the B

y = mx + b
y = -3x + 12 -- the answer
