Select the correct choice below and fill in the answer box(es) to complete your choice.
OA. The slope of y=f(x) is
and the slope of y = g(x) is
(Simplify your answers.)
. Since the product of their slopes is not-1, lines y = f(x) and y = g(x) are not parm
OB. Since both lines have a slope of , lines y=f(x) and y = g(x) are parallel.
and the slope of y = g(x) is
(Simplify your answer.)
OC. The slope of y=f(x) is
(Simplify your answers.)
OD. The slope of y=f(x) is
(Simplify your answers.)
and the slope of y = g(x) is
Since the slopes are different, lines y=f(x) and y = g(x) are not parallel.
Since the product of their slopes is -1, lines y=f(x) and y=g(x) are parallel.
