Question

Can you guys please help me with math? (Pt 2.)

Answer 1

Let

x--------> the length side of the rectangle

y-------> the width side of a rectangle

we know that

$y=\frac{1}{2}x$ ------> equation A

$x=2a\ units$ ---------> given problem (see the graph)

substitute the value of x in the equation A

$y=\frac{1}{2}2a=a\ units$

therefore

the answer is

the top-left vertex of the rectangle is the point $(0,a)$

Answer 2

(0,a)

it didnt move left or right on the x-axis
it went up a units (since its half of 2a)
