Answer:

y = 4x - 1

Step-by-step explanation:

(1, 3) ; (2 ,7 )

$Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{7-3}{2-1}\\\\=\frac{4}{1}\\\\= 4\\\\\\y - y_{1} = m(x -x_{1})\\\\y - 3 = 4(x - 1)\\\\y - 3 =4x - 4\\ y = 4x - 4 + 3\\y = 4x - 1$

$\dfrac{dy}{dx}\ \ln\left(\dfrac{x}{x^2+1}\right)=\dfrac{1}{\frac{x}{x^2+1}}\cdot\dfrac{x'(x^2+1)-x(x^2+1)'}{(x^2+1)^2}\\\\=\dfrac{x^2+1}{x}\cdot\dfrac{1(x^2+1)-x(2x)}{(x^2+1)^2}=\dfrac{1}{x}\cdot\dfrac{x^2+1-2x^2}{x^2+1}=\dfrac{1-x^2}{x^3+x}\\\\Used:\\\\(\ln(x))'=\dfrac{1}{x}\\\\\left[f(g(x))\right]'=f'(g(x))\cdot g'(x)\\\\\left(\dfrac{f(x)}{g(x)}\right)'=\dfrac{f'(x)g(x)-f(x)g'(x)}{[g(x)]^2}$
