Find Integrating Fector: <br> ylogy dx + ( x-logy )dy=0
12345 [234]
Rewrite the ODE as

y\log y\,\mathrm dx+(x-\log y)\,\mathrm dy=0\iff y\log y\dfrac{\mathrm dx}{\mathrm dy}+x=\log y
\dfrac{\mathrm dx}{\mathrm dy}=\dfrac1{y\log y}x=\dfrac1y

so that it is now linear in x. An integrating factor would

\mu(y)=\exp\left(\displaystyle\int\frac{\mathrm dy}{y\log y}\right)=e^{\log(\log y)}=\log y

Multiply both sides by \mu(y) to get

\log y\dfrac{\mathrm dx}{\mathrm dy}=\dfrac1yx=\dfrac{\log y}y
\dfrac{\mathrm d}{\mathrm dy}[x\log y]=\dfrac{\log y}y
x\log y=\displaystyle\int\frac{\log y}y\,\mathrm dy
x\log y=\dfrac12\log^2y+C
x=\dfrac12\log y+\dfrac C{\log y}

what is the equation of a line in slope-intercept form having a slope of -3 and a y-intercept of -2?​
lutik1710 [3]

Answer:

The equation is y=-3x-2

Step-by-step explanation:

The first we need to know is the equation of a line, and it is y=mx+b

where the m is the slope and b is the interception to the y axis

With the information in the question the slope is -3 and the equation thats equal to m. and the y intercept of -2 thats equal to the b value

then y=-3x-2
