What is the equation of the line that passes through the points {1,1/2} and (-1,-1)
Feliz [49]

Anytime we need to get the equation of a line, we need 2 things:

<span><span> <span>a point </span></span>a slopeSo, what do we do if we are just given 2 points and no slope?No problem -- we'll just use the 2 points to pop the slope using this guy:
</span>

Check it out:

Let's find the equation of the line that passes through the points

<span>(1,1/2) and (-1,-1)

</span>

This one's a 2-stepper...

<span>STEP 1:<span>  </span>Find the slope</span>

<span>STEP 2:<span>  </span>Now, use the point-slope formula with one of our points,<span> </span></span>

Write each expression as an equivalent expression with a single logarithm. Assume xx, yy, and zz are positive real
Debora [2.8K]

Answer:

\ln\frac{xy^2}{z^3}

Step-by-step explanation:

Data provided:

ln(x) + 2 ln(y) − 3 ln(z)

Now,

From the properties of log function,

ln(A) + ln(B) = ln(AB)

n × ln(x) = ln(xⁿ)

and,

ln(A) - ln(B) = \ln\frac{A}{B}

applying the properties in the given equation

we get

⇒  ln(x) + 2 ln(y)  − 3 ln(z)

or

⇒ ln(x) + ln(y²) - ln(z³)            (using n × ln(x) = ln(xⁿ))

or

⇒ ln(xy²) - ln(z³)                    (using ln(A) + ln(B) = ln(AB) )

or

⇒ \ln\frac{xy^2}{z^3}   (using ln(A) - ln(B) = \ln\frac{A}{B} )
