Answer:
when the negative is outside of the parenthesis like in
-(-(2)) you need to distribute the negative to all the numbers within the parenthesis.
so in the case of -(-(2)) the first negative would distribute inside the parenthesis making the answer positive 2

Completing the square has us breaking rules of solving equations and factoring out the greatest common factor, but it is what it is! The first step is to make sure that the coefficient on the x^2 term is a 1 and it is so we are good there. Now subtract 9 from both sides to get x^2 + 16x = -9. Complete the square on the left side by taking half of the linear term (16x) which is 8 and then squaring it to get 64. That's what is added to both sides. Now it looks like this:
x^2 + 16x + 64 = -9 + 64. If you were to write it in vertex form it would look like this: (x+8)^2 - 55 = 0. Now you can use this to plot the vertex of a parabola if you want to: it sits at (-8, -55)

1. To find the slope do the rise/sun. So you need to create a right triangle by connecting the points. If the line goes from left to right than it is a negative slope. But if it goes from right to left than it is a positive slope. Count how many down from the top point to the bottom and then count how many to connect the 2. But the points you give make a straight line. Meaning the slope is 0. Hope someone answer the rest of your questions because this is the only one I know!
