Write the point-slope form of the equation for a line that passes through (6, -1) with a slope of 2

defon

ANSWER

$y + 1=2(x-6)$

EXPLANATION

The point-slope form of a line is given by;

$y-y_1=m(x-x_1)$

where

$m = 2$

is the slope of the line and (6,-1) is point.

We substitute the point and the slope into the formula to obtain:

$y + 1=2(x-6)$

Hence the b point slope form of the line with the given properties is

Find the sum of the first 100 terms in the series

iVinArrow [24]

Hello,

$\dfrac{1}{n} - \dfrac{1}{n+1} = \dfrac{1}{n(n+1)} \\

 \dfrac{1}{1*2} = \dfrac{1}{1} - \dfrac{1}{2} \\

 \dfrac{1}{2*3} = \dfrac{1}{2} - \dfrac{1}{3} \\

 \dfrac{1}{3*4} = \dfrac{1}{3} - \frac{1}{4} \\

...\\
 \dfrac{1}{n*(n+1)} = \dfrac{1}{n} - \dfrac{1}{n+1} \\



$

Adding member by member, we have

$\dfrac{1}{1*2} + \dfrac{1}{2*3} +\dfrac{1}{3*4} +...\dfrac{1}{n*(n+1)}=\\
 
\dfrac{1}{1} - \dfrac{1}{n+1} \\

= \dfrac{n}{n+1} \\

$

if n=100 sum $\boxed{= \dfrac{100}{101} }$
