If ln(4x+y)=2x-3,then dy/dx=

Viktor [21]

$\ln(4x+y)=2x-3$

Differentiate both sides wrt $x$ :

$\dfrac{\mathrm d(\ln(4x+y))}{\mathrm dx}=\dfrac{\mathrm d(2x-3)}{\mathrm dx}$

By the chain rule, we get

$\dfrac1{4x+y}\dfrac{\mathrm d(4x+y)}{\mathrm dx}=2$

$\dfrac{4+\frac{\mathrm dy}{\mathrm dx}}{4x+y}=2$

Solve for $\frac{\mathrm dy}{\mathrm dx}$ :

$4+\dfrac{\mathrm dy}{\mathrm dx}=8x+2y$

$\boxed{\dfrac{\mathrm dy}{\mathrm dx}=8x+2y-4}$

A line includes the points (-3, 8)and (-1, 2). What is its equation in slope- intercept form

Natasha_Volkova [10]

Solve for slope first:
m = $\frac{y2 - y1}{x2 - x1}$

m = $\frac{2-8}{-1-(-3)}$ = -3

then solve for b in y = mx + b

8 = -3(-3) + b
b = -1

y = -3x - 1
