Equation of a line in slope-intercept form:

$y=mx+b$

m is the slope

b is the y-intercept

As you have the slope (m= -4) and a point (6,1) you use it in the equation above to find the y-intercept, as follow:

(6,1) x=6 y=1

m= -4

$1=-4(6)+b$

Solve b:

$\begin{gathered} 1=-24+b \\ \\ 1+24=-24+24+b \\ 25=b \end{gathered}$ Then, the equation of the given line in slope-intercept form is: $y=-4x+25$

Answr :

I hope my answer is correct

m<Jmk = m<HML. m<HJL=m<KHJ

m<JKH=m<JHL m<LHK=m<JLH

m<HLK = m<HJK. m<JLK= m< HJL

Can somebody do this without a calculator please?

zavuch27 [327]

$\frac{1}{f} = \frac{1}{u} + \frac{1}{v}$
multiply f to the entire equation
$1= \frac{f}{u}+\frac{f}{v}$
add up right side

$1=\frac{fv}{uv} +\frac{fu}{uv}$
$1= \frac{fv+fu}{uv}

$

multiply uv to both sides
$uv= fv+fu$
factor out f
$uv= f(v+u)$
divide (v+u) to both sides
$\frac{uv}{v+u}=f$

substitute in u=3.5cm and v=-4 cm
