Answer 1

`\begin{gathered} 12.\text{Point }1\text{ (}3,8\text{)} \\ \text{relationship =}(8)/(3) \\ \text{Point 4 (}9,24\text{)} \\ \text{relationship =}(24)/(9) \\ \text{relationship =}(8)/(3) \\ \text{The equation that represents the proportional relationship is y=}(8)/(3)x \\ \\ 10.\text{ } \\ \text{Point }1\text{ (}3,8\text{)} \\ \text{relationship =}(8)/(3) \\ \text{Point 2 ( }6,15\text{)} \\ \text{relationship =}(15)/(6) \\ \text{relationship =}(5)/(2) \\ \text{Point 3 ( 8},21\text{)} \\ \text{relationship =}(21)/(8) \\ \text{Point 4 (}9,24\text{)} \\ \text{relationship =}(24)/(9) \\ \text{relationship =}(8)/(3) \\ The\text{ points (}3,8\text{) and (}9,24\text{) represent the same proportional relationship} \\ \\ 11. \\ \text{the constant of proportiona}lity\text{ is }(8)/(3) \end{gathered}`
