Know the various forms for writing linear
equations.
Understand and define proportional
relationships/ direct variations
The slope of a line represents a constant rate of
change between the dependent and independent
variable.
Parallel lines have equal slopes and different yintercepts.
The slope of a line parallel and perpendicular to
the x- and y- axis
Identify the slope and y-intercept given any
multiple representations such as tables, graphs,
equations and verbal descriptions.
The correlation coefficient shows how well a
linear regression fits a set of data.
Students will need to relate writing linear
inequalities with writing linear equations,
understanding which inequality symbol should be
used

X: beginning of unit
O: after lesson
*: before test
Write and solve an equation of a line in
various forms given multiple representations.
(Graph, table, verbal representation, a point
and a slope, or a slope and y-intercept)
Write and solve equations involving direct
variation, and use direct variation to solve
real-life problems.
Use slope to identify parallel and
perpendicular lines.
Students use their knowledge of parallel and
perpendicular slopes and their knowledge of
linear equations to write an equation of a line.
Write linear and solve inequalities in two
variables given multiple representations.
(Graph, table of values, and a verbal
representation)
Calculate the slope of a line when given an
equation in standard form, slope -intercept
form, point slope form, or any two points on
the line.
Use algebraic methods and
technology to fit a linear
function to the data and to
make predictions.
Create a scatter plot from
two quantitative variables
and describe the form,
strength and direction of
the relationship.
