Answer 1

$\textbf{Formula used:}$

$\text{The distance between two points }[tex][tex](x_1,y_1)\:\text{and}\:(x_2,y_2)$$\text{is}$

$\bf\;d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$

$\text{Given points are A(7,4) and B(3,y)}$

$\text{Given:}$

$\text{The distance between A and B is 4}$

$\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}=4$

$\implies\sqrt{(7-3)^2+(4-y)^2}=4$

$\implies\sqrt{16+(4-y)^2}=4$

$\text{Squaring on both sides}$

$\implies\;16+(4-y)^2=16$

$\implies\;(4-y)^2=0$

$\implies\;4-y=0$

$\implies\boxed{\bf\;y=4}$

$\therefore\textbf{The value of y is 4}$
