Answer:
[tex]the \: slope \: is \: - 2.[/tex]
Step-by-step explanation:
[tex]you \: are \: asked \: to \: find \: the \: slope, \\ \: but \: the \: slope \: of \: two \: pionts \: has \: a \: formula : \\ m = \frac{y_{2} - y_{1} }{x_{2} - x_{2}} \\ since : \\ y_{2} =5 \\ y_{1} = - 19 \\ x_{2} = - 15 \\ x_{1} = - 3, \: then : \\m = \frac{5 - ( - 19)}{( - 15) - ( - 3)} = \frac{24}{ - 12} \\ m = - 2.[/tex]
