Find the slope of the line passing through the points (1, -1) and (4, -2).

vagabundo [1.1K]

Answer:

$slope=-\frac{1}{3}$

Step-by-step explanation:

To find the slope of the two points (1, -1) and (4, -2) we have to use the slope formula.

$slope=\frac{y_{2}- y_{1} }{x_{2} -x_{1} }$ $slope=\frac{(-2)- (-1)}{4 -1}$

$slope=\frac{-1 }{3}=-\frac{1}{3}$ can also be written as a decimal $slope=-0.333333$
