Question

find the slop of the line AB if A(8,-9) and B(-5,3)

Answer 1

Slope of a line is :

$\mathsf{m=\frac{y_2-y_1}{x_2-x_1}}$

Given :

$x_1=8$

$x_2=-5$

$y_1=-9$

$y_2=3$

$\textsf{Slope = }\mathsf{\frac{y_2-y_1}{x_2-x_1}}$

$\implies\mathsf{\frac{3-(-9)}{-5-8}}$

$\implies\mathsf{\frac{12}{-13}}$

$\textsf{\huge{\underline{\underline{\boxed{ANSWER}}}}}}$

$\textsf{The slope of the line is}\mathsf{-\frac{12}{13}}$

Hope it helps !
