You could put 7 groups of 3 or vice versa. I am not sure of any other answer.
Answer:
Y= 5
Step-by-step explanation:
14+13Y=20Y-21
-13y -13y
14=7y-21
+21 +21
35/7=7y/7
y=5
The slope is 6/3 or 2 because you are rising 6 and run is 3, you can simplify and 6/3 to 2. and the equation is y=2x-3
That should be right, because the absolute value of -9 would be 9, but the negative sign in front makes it -9.
