Question

Find y if distance between points J (5, y) and K (-7, -3) is 13​

Answer 1

Step-by-step explanation:

According to the question

${:}\longrightarrow$

J-K=13

$\implies{(5,y)-(-7,-3)=13} \\ \implies{5-(-7-3)+y(-7-3)}{=13}$

$\implies{5-(-10)+y(-10)} \\ \implies{5+10+y+10=13} \\ \implies{25+y=13} \\ \implies{y=13-25}$

${:}\longrightarrow$${\underline{\boxed {\bf{y=-12}}}}$
