Hey there!
The answer to your question is y = -3/7x - 9/7
To answer this, we need to get y by itself on one side, so we need to solve for y:
3x - 7y = 9
-7y = 3x + 9
y = -3/7x - 9/7
Hope it helps and have an amazing day!

Step-by-step explanation:
The midpoint is 1. Between A and B, there are a total of 14 marks on the number line. If you start at -6 and move up 7 marks, you will land on 1. The number 1 is in the middle of -6 and 8.
Answer:
First side is 19, second side is 38 and third side, the longest is 43.
Step-by-step explanation:
Let's call the first side a.
The second side, being twice as long as the first, is 2a.
The third side is 2a+5.
The equation is:
a+2a+2a+5=100, since 1 metre is 100 centimetre.
5a+5=100
5a=95
a=19
First side is 19, second side is 38 and third side, the longest is 43.
