A.2A
Determine the domain and range of a linear function in mathematical problems; determine reasonable domain and range values for real-world situations, both continuous and discrete; and represent domain and range using inequalities.
A.2B
Write linear equations in two variables in various forms including y = mx +b, Ax + By = C, and y – y1 = m(x – x1) given one point and the slope and given two points.
A.2C
Write linear equations in two variables given a table of values, a graph, and a verbal description.
A.2D
Write and solve equations involving direct variation.
A.2E
Write the equation of a line that contains a given point and is parallel to a given line.
A.2F
Write the equation of a line that contains a given point and is perpendicular to a given line.
A.2G
Write an equation of a line that is parallel or perpendicular to the X or Y axis and determine whether the slope of the line is zero or undefined.
A.2H
Write linear inequalities in two variables given a table of values, a graph, and a verbal description.
A.2I
Write systems of two linear equations given a table of values, a graph, and a verbal description.
