120 or it's 60 (: i think because if it's' 60 then you just add the 15 to 45 but if it's 120 then you multiply 60 ny 2

Based on the table of values below, find the slope between points where x = 1 and where x = 4.

$\bf \begin{array}{llll}
x&\boxed{1}&3&\boxed{4}\\\\
y&\boxed{8}&6&\boxed{-1}
\end{array}\\\\
-------------------------------\\\\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 1}}\quad ,&{{ 8}})\quad 
% (c,d)
&({{ 4}}\quad ,&{{ -1}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-1-8}{4-1}\implies \cfrac{-9}{3}\implies -3$
