Question 1

I need help in this one

Question 2

$\bf \begin{array}{ccllll} \begin{array}{cllll} HCF\\ x \end{array} & \begin{array}{cllll} \$\\ y \end{array}\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ 19&31.91\\ 47&69.71 \end{array}\\\\ -----------------------------\\\\ \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ 19}}\quad ,&{{ 31.91}})\quad % (c,d) &({{ 47}}\quad ,&{{ 69.71}}) \end{array}$

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{69.71-31.91}{47-19} \\\\\\ m=\cfrac{rise}{run}\implies \cfrac{37.8}{26}\iff \cfrac{189}{130} \\\\\\ \textit{now, what if HCF is 35? HCF is$
