Write the equation of the line that passes through the point (-5,5) and has a slope of -8/5

Free_Kalibri [48]

Answer:

The equation of the line that passes through the point (-5,5) and has a slope of -8/5 will be:

$y=-\frac{8}{5}x-3$

Step-by-step explanation:

Given

$\left(x_1,\:y_1\right)=\left(-5,5\right)$

$m=\frac{-8}{5}$

Point-Slope Form equation is

$\left(y-y_1\right)=m\left(x-x_1\right)$

$\left(y-5\right)=\frac{-8}{5}\left(x-\left(-5\right)\right)$

$\mathrm{Apply\:rule}\:-\left(-a\right)=a$

$y-5=\frac{-8}{5}\left(x+5\right)$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}$

$y-5=-\frac{8}{5}\left(x+5\right)$

$y-5+5=-\frac{8}{5}\left(x+5\right)+5$

$y=-\frac{8}{5}x-3$

Therefore, the equation of the line that passes through the point (-5,5) and has a slope of -8/5 will be:

$y=-\frac{8}{5}x-3$

What is an equation of the line that passes through the points (-6,-3) and (-3,-5)

Murrr4er [49]

Answer:

y = - $\frac{2}{3}$ x - 7

Step-by-step explanation:

A( $x_{1}$ , $y_{1}$ ) , B( $x_{2}$ , $y_{2}$ )

y - $y_{1}$ = m( x - $x_{1}$ )

m = $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

~~~~~~~~~~~~~

( - 6, - 3 )

( - 3, - 5 )

m = $\frac{-5+3}{-3+6}$ = - $\frac{2}{3}$

y + 5 = - $\frac{2}{3}$ ( x + 3)

y + 5 = - $\frac{2}{3}$ x - 2

y = -  $\frac{2}{3}$  x - 7
