(19,-9) (-7,-15) in slope intercept form

never [62]

Answer:

$y=\frac{3}{13}x-\frac{174}{13}$

Step-by-step explanation:

slope:

$m=\frac{-15-(-9)}{-7-19} =\frac{-15+9}{-26} =\frac{-6}{-26} =\frac{3}{13}$

Equation, with the point (19, -9):

$y-(-9)=\frac{3}{13} (x-19)$

$y+9=\frac{3}{13} x-\frac{57}{13}$

$y=\frac{3}{13} x-\frac{57}{13} -9$

$-9=-9(\frac{13}{13} )=-\frac{117}{13}$

$y=\frac{3}{13}x-\frac{174}{13}$

Hope this helps
