3x-y=1

someone:

I believe that slope intercept form is

y= mx+b correct?

If so, just do some simple algebra:

x-7y=7
-7y=7-x
7y=-7+x
y=x/7-1
y=(1/7)x-1

percent means "part of one hundered" which means that 73% is 73 parts of 100 or 0.73.
You can now just multiply 13 by 0.73 and get 9.49

Using the Pythagorean Theorem, I am trying to find what 4.2 squared times (I think that you mean plus) 6.5 squared is. I keep coming up with the answer 62.5. Is this correct?
