Draw the line $x=1$ on a grid. Label this line $L.$ Also draw a line parallel to line $L$ and $3.5$ units away from $L.$ Draw a line perpendicular to $L$ that passes through $(1, 4.5)$. Write the equation for perpendicular line.

Draw the line $x=1$ on a grid. Label this line $L.$ Also draw a line parallel to line $L$ and $3.5$ units away from $L.$ Draw a line perpendicular to $L$ that passes through $(3.5, 1.5)$. Write the equation of this line.

On a grid , draw these four lines and find the area of the square made by these four lines.

$x=3, y=5, x=-3, y=-1$

Draw four lines that enclose a rectangle with an area of $18$ units. Write down the equations of four lines 

Two lines parallel to the $x-$axis and two lines parallel to the $y-$axis make a square. The centre of the square is at origin $\left(0, 0\right)$. Each side of the square is $8$ units.

Find the equation of each of the four lines.
