Explain each step in solving
a simple equation as
following from the equality of
numbers asserted at the
previous step, starting from
the assumption that the
original equation has a
solution. Construct a viable
argument to justify a solution
method.
A-REI.11
Explain why the xcoordinates of the points
where the graphs of the
equations y = f(x) and y =
g(x) intersect are the
solutions of the equation f(x)
= g(x); find the solutions
approximately, e.g., using
technology to graph the
functions, make tables of
values, or find successive
approximations. Include
cases where f(x) and/or g(x)
are linear, polynomial,
rational, absolute value,
exponential, and logarithmic
functions. ★

Use the structure of an
expression to identify ways to
rewrite it. For example, see x4 –
y4 as (x2)2 – (y2)2, thus
recognizing it as a difference of
squares that can be factored as
(x2 – y2)(x2 + y2). Write
expressions in equivalent forms
to solve problems

Calculate and interpret the
average rate of change of a
function (presented symbolically
or as a table) over a specified
interval. Estimate the rate of
change from a graph. ★

Represent transformations in
the plane using, e.g.,
transparencies and geometry
software; describe
transformations as functions
that take points in the plane as
inputs and give other points as
outputs. Compare
transformations that preserve
distance and angle to those that
do not (e.g., translation versus
horizontal stretch).
G.CO.9
Prove theorems about lines and
angles. Theorems include:
vertical angles are congruent;
when a transversal crosses
parallel lines, alternate interior
angles are congruent and
corresponding angles are
congruent; points on a
perpendicular bisector of a line
segment are exactly those
equidistant from the segment’s
endpoints.
