I keep getting different answers and none of them equal -2 when I check my work, can someone help.

Ok, Im learning about graphing and I cant get ahold of my teacher to ask her this question so I thought I would bring it here. Im trying wright the equation of a line with given slope and y-intercept.
This is the question.

Slope: -2; y-intercept: (0, 4)

I believe if you turned this into a equasion you would have
y= -2x + 4

Now this is where I think I am messing up. When you plot this on a graph I go to (0,4) and then I go back 2 points to make -2. This would create a strait line. Is this correct?

the problem says that the eigenvalues are all nonnegative, so you don't need to check that, simply what happens when λ=0 and when λ is positive.

Then says, determine if λ=0 is an eigenvalue, then find the positive eignvalues and associated eigenfunctions.

I've tried this several times, but can't quite figure out what I'm doing wrong.

btw the answer in the book says:

Eigenvalue λ[subscript 0]=0 with eigenfunction y[subscript ](x) ≡ 1, and positive eigenvalues {n^2} with associated eigenfunctions {cos nx} for n=1,2,3...

What can we abserve from the reaction?what can we conclude from the experiment?

Concentration of reactants:Magnesium-Hydrochlor... acid system

1.the magnesium strip is add into different mole of Hydrochloric acid which is 6M, 4M, 3M and 1M.
2.Record the time for completion of the reaction.
Add the first magnesium strip to the 6M HCL solution,the time was recorded for all traces of the magnesium strip to disappear and repeat with 4M, 3M and 1M.

I live in South Eastern Connecticut and I have never seen a moth that looks like these do. I think they are very beautiful and unique. Can anyone tell me what kind that are? I've searched the internet but couldn't find anything with this coloring.
