Question

What is the slope of the line between (-4, 4) and (-1, -2)

how do i do problems like these not really looking for a answer i just want to learn it

Answer 1

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&(-4\quad ,&4)\quad &(-1\quad ,&0-2)
\end{array}
\\\quad \\

slope = m= \cfrac{rise}{run} \implies \cfrac{y_2-y_1}{x_2-x_1}
\\ \quad \\

y-y_1=m(x-x_1)\quad \textit{plug in your values and solve for "y"}\)

Answer 2

\[slope = \frac{ (y _{2} -y _{1})}{ (x _{2}- x _{1}) }\]

Answer 3

hmm \(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&(-4\quad ,&4)\quad &(-1\quad ,&-2)
\end{array}
\\\quad \\

slope = m= \cfrac{rise}{run} \implies \cfrac{y_2-y_1}{x_2-x_1}
\\ \quad \\

y-y_1=m(x-x_1)\quad \textit{plug in your values and solve for "y"}\)
