Question

# 4. How do I find the slope of QR and ST.

Answer 1

looks like you did just fine.. .the only part is the sign for the slope, is all


`\bf \textit{slope of }\overline{QR}\implies \cfrac{-2b}{2c-2a}\implies \cfrac{-b}{c-a}\iff \cfrac{b}{a-c} \\\\\\ \textit{slope of }\overline{ST}\implies \cfrac{0-b}{c-a}\implies \cfrac{-b}{c-a}\iff \cfrac{b}{a-c}`
