ganeshie8 · Answer

$$ slope = \frac{y2-y2}{x2-x1}$$

slope is +ve : line rises
slope is -ve : line falls
slope is 0 : line is horizontal
slope is 1/0 : line is vertical

ganeshie8 · Answer

(8,2), (5,-3)
$$ slope = \frac{-3-2}{5-8} = \frac{-5}{-3} = \frac{5}{3}$$ 

slope is +ve . so line rises
