exis [7]

Answer:

$Tan \theta= \dfrac{4}{3}$

Step-by-step explanation:

Given:

The terminal side of an angle in standard position passes through P(-3,-4).

Point P is in Quadrant III
In Quadrant |||, $Tan \theta$ is positive.

$Tan \theta= \dfrac{Opposite}{Adjacent}\\Tan \theta= \dfrac{y}{x}\\Tan \theta= \dfrac{-4}{-3}\\Tan \theta= \dfrac{4}{3}$
