What is the slope of the line through the points (-3,3) and (6,-8)
STatiana [176]

Answer:

\displaystyle \frac{-11}{9}

Step-by-step explanation:

       We will use the equation of change in y over change in x to solve for the slope of the line. Then, we will simplify.

\displaystyle \frac{y_{2}-y_1 }{x_2-x_1}

\displaystyle \frac{-8-3}{6--3}

\displaystyle \frac{-8-3}{6+3}

\displaystyle \frac{-11}{9}
