\Large\maltese\underline{\textsf{A. What is Asked}}

What is the slope of a linear function that goes through (8,-8) and (5,-1)?


\Large\maltese\underline{\textsf{B. This problem has been solved!}}

Formula utilised, here
\bf{(y2-y1)/(x2-x1)}.

We utilise that formula because we have two points as our given information.

So, we

put in the values


\bf{(-1-(-8))/(5-8)} | subtract on top and bottom


\bf{(-1+8)/(-3)} | simplify


\bf{(7)/(-3)


\cline{1-2}


\bf{Result:}


\bf{=Slope=-(7)/(3)}


\LARGE\boxed{\bf{aesthetic\\ot1\theta l}}

Hey there!

  • Answer :


\sf{ \purple{ \boxed{\bold{m = - (7)/(3) }}}}


\\

  • Explanation :

We are given the points
\sf{P_1(\overbrace{ \blue{8}}^{\blue{x_1}} ,\underbrace{\orange{-8}}_{ \orange{y_1}}) \: and \: P_2(\overbrace{ \green{5}}^{\green{x_2}} ,\underbrace{\red{-1}}_{\red{y_2} })} . To find the slope
\sf{\purple{m}} of such a line, we use the slope formula which is the following:


\sf{ \purple{m} }= (\Delta y)/(\Delta x) = \frac{ \red{y_2} - \orange{y_1}}{ \green{x_2 }- \blue{x_1}}


\\

⇢Now, by plugging in our values, we get :


\sf{ \purple{m}} = \frac{ \red{ - 1} - \orange{( - 8)}}{ \green{5} \: - \: \blue{8}} = ( \: \: 7 \: )/( - 3 \: ) \\ \\ \implies \sf{ \purple{ \boxed{m = - (7)/(3) }}}

Therefore, the slope of the line is
\sf{ \purple{ \boxed{m = - (7)/(3) }}}
