let
x----------> the length side of a square
y----------> the width side of a square
we know that
the length side of a square is equal to the width side of a square
so
y=x
and y=x------> is the equation of a line
see the attached figure
so
A. The graph would be a line--------> is true
B. The graph would pass through the origin -----> is true
C. The graph would rise from left to right -----> is true
D. The shape of the graph would be curved----> is not true---> Is a straight line
therefore
the answer is
the option D is not true
D. The shape of the graph would be curved
