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.
The equation of the graph is given as y = (2/5)x - 5.
You have to figure out which of the choices equals the equation given, y = (2/5)x - 5. You could solve each of the answer choices for y, but since each choice is in the format x - (m)y = b, you can put the given equation in that format too.
Answer: No, the side lengths of 5, 5 and 10 would not be able to.
So the answer is FALSE.
This is because all the lengths must be enough so that when you add the side lengths they are greater then the other, all would work accept 5+5 is not greater than 10.
