Y = 3x - 1
The format for slope intercept form is:
y = mx + b
m represents the slope and that was given so:
y = 3x + b
Now we have to substitute the value from the given point into “y” and “x” to solve for “b”
(2) = 3(1) + b
2 = 3 + b
-1 = b
Now that we know b we can substitute it into y = 3x + b to get the equation of the line
y = 3x - 1
~~hope this helps~~
I think the mean is 186 and then after rounding it to the nearest 10 it turns 190
Divide both sides by 
:
![x\dfrac{\mathrm dy}{\mathrm dx}+y=\dfrac{\mathrm d}{\mathrm dx}[xy]=-\dfrac{\sec(xy)}{x^3}](https://tex.z-dn.net/?f=x%5Cdfrac%7B%5Cmathrm%20dy%7D%7B%5Cmathrm%20dx%7D%2By%3D%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Bxy%5D%3D-%5Cdfrac%7B%5Csec%28xy%29%7D%7Bx%5E3%7D)
Integrate both sides to get
where 
and 
are constants, and divide by 
to solve for

An exact solution (not in terms of a definite integral, anyway) doesn't seem likely...
