Answer 2

Answer:

$\huge\bold\red{ANSWER}$

Step-by-step explanation:

→  $\blue{\bold{\underline{\underline{SOLUTION}}}}$

$\implies \sf i)\: M(2,8)\\ \\ B(-4,19)\\ \\ So, \: asking\:to\:find\:A\\ \\ \implies \sf M=\frac{A+B}{2}\\ \\2M=A+B\\ \\ 2M-B=A\\ \\ 2(2,8)-(-4,19)=A\\ \\ (4,16)-(-4,19)=A\\ \\ (8,-3)=A$

$\implies \sf ii)B=2M-A\\ \\ B=2(-2,4)-(-1,2)\\ \\ B=(-4,8)-(-1,2)\\ \\ B=(-3,6)$
