I still don't get it does that mean b=3

So they would be Parallel correct? Thank you

That does not come out right.

I did that wrong c=2d for d the solution is d= c /2 Correct

if a=3b for b The solution is b =a/3 Do I understand this correctly now?

so what is y= then?

it also says im supposed tp find an equation of the line containing the given pair of points?

Thanks! got it.

5 waves pass in 26 seconds, period = 26 sec / 5 waves = 5.2 seconds, f = 0.192 hz

If I1 is the intensity at a distance 150 m from the source and I2 is the intensity at a distance of d m from the source , I1 *150^2 = I2 *d^2 d^2 =[ I1 / I2 ]*150^2 [I1 / I2] = 1.9 /0.8= 2.375 d^2 = 2.375*150^2 d =231.17 m.
