There's the obvious vertical one, y=2, and the other one you can say has equation:
y-2=m(x-1)
Where m is the gradient.
The line perpendicular to this is y= -x/m , so the way i did it was to say that you know that where these two lines meet, x^2 + y^2 = 1, by Pythagoras's Theorem.
So then you can set up simultaneous equations and work through some really complicated algebra and the answer does eventually come out, but i was just wondering if there is a better way than that? Can anyone help?

I would like you to give your best effort in presenting evidence to me that we never landed on the moon. No links to websites or videos, just your own words. Once I have your answers, keep checking back, as I send rebuttals to your evidence. I still can't believe ppl buy into this conspiracy hoax.

I picture the fabic of space as a sheet being stretched out with the mass of planets and such causing dimples in it which anything else on the fabric has the tendency to fall into.

This sheet stretching also pulls the the bodies of mass along with it as it stretchs, expansion of the universe.

But to think of space as a sheet is two dimensional. The only places where the dimensions change is where there are high concentrations of matter.

Mass does warp space and time doesn't it?

Consider the following titration reaction:

2 NaOH + H2A ------> Na2A + 2 H2O

Where H2A is your unknown acid. If 32.18 mL of 0.126 M NaOH are required to titrate a 0.0783g sample of the acid, what is the molar mass of your acid?

a. 38.62 g/mol
b. 77.24 g/mol
c. 19.31 g/mol
d. 42.78 g/mol

Please tell me how to find the Molar Mass
