Check the picture below

so.. .if we use those 2 points, from the "best fit line"

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 10}}\quad ,&{{ 20}})\quad 
% (c,d)
&({{ 20}}\quad ,&{{ 40}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{40-20}{20-10}\implies \cfrac{20}{10}\implies 2$

$\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\qquad 
\begin{array}{llll}
\begin{cases}
y_1=20\\
x_1=10\\
m=2
\end{cases}\\
\end{array}\implies y-20=2(x-10)\\
\left. \qquad \right. \uparrow\\
\textit{point-slope form}
\\\\\\
y-20=2x-20\implies y=2x-20+20\implies \boxed{y = 2x}$

Antoine and Tess have a disagreement over how to compute a 15% gratuity on $46.00. Tess says, “It is easy to find 10% of 46 by moving the decimal point one place to the left to get $4.60. Do that twice. Then add the two amounts to get $4.60 + $4.60 = $9.20 for the 15% gratuity.” How should Antoine respond to Tess’s method?
