Question

Find the slope of the line that passes through pairs of points.

(-5.5, 6.1), (2.5, 3.1)

a.) 3/8
b.) -1
c) 1
d.) -3/8

I'm getting a major headache from this math.. please help.

Answer 1

\[\huge \frac{6.1-3.1}{-5.5-2.5}\]

Answer 2

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ -5.5}}\quad ,&{\color{blue}{ 6.1}})\quad &({\color{red}{ 2.5}}\quad ,&{\color{blue}{ 3.1}})
\end{array}
\\\quad \\

slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ y_2}}-{\color{blue}{ y_1}}}{{\color{red}{ x_2}}-{\color{red}{ x_1}}}\)

Answer 3

still not getting it..
