Mrs.
Fields’
science
class
takes
care
of
a
plant
at
school.
The
class
is
responsible
for
watering
the
plant
and
measuring
its
growth.
The
students’
measurements
are
charted
in
the
table.

Months

of
the
Plant

Which
of
the
following
equations
relates
the
height
of
the
plant,
A,
and
the
number
of
months,
m,
assuming
a
constant
rate
of
growth?
A
4m
=
h
B
m+3=h
\/
The
difference
between
the
growth
of
each
month
is
5
inches;
locking
at
the
growth
of
each
month,
the
plant’s
height
increases
5
inches
each
month.
If
the
rate
of
growth
is
constant,
then
the
beginning
height
of
the
plant
is
3
inches;
the
height
at
the
first
month
(8
inches)
minus
the
growth
of
that
month
(5
inches)
would
equal
3
inches.
If
the
growth
of
each
month
is
5
inches,
then
one
can
find
the
height
of
the
plant
by
the
growth
of
each
month
(5
inches)
multiplied
by
the
month
(m)
and
then
add
3
inches
to
account
for
the
initial
height.
