Please help meeee I don't know this
Vanyuwa [196]

Answer:

\boxed {m = -\frac{5}{7}}

Step-by-step explanation:

Use the <u>Slope Formula</u> to determine the slope of two given points:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

First Point: (x_{1} , y_{1})

Second Point: (x_{2}, y_{2})

-Substitute both points:

First Point: (5, 11)

Second Point: (19, -1)

m = \frac{-1 - 11}{19 - 5}

-Solve for the slope:

m = \frac{-1 - 11}{19 - 5}

m = \frac{-10}{14}

\boxed {m = -\frac{5}{7}}

Therefore, the slope is -\frac{5}{7}
