A.6 The student will
c) graph linear equations in two variables.
- I can master the challenge of
a ski slope for snowboarding, determine the gradient of a road, figure the pitch
of a roof, and build a handicap accessible ramp to a door.
- I will understand slope is rate of change where one value
changing proportionately effects the other value, and the pattern of this
relationship can be represented by a line that facilitates analysis and
UNDERSTANDING THE STANDARD
· Changes in slope may be described by dilations or reflections or both.
· Changes in the y-intercept may be described by translations.
· Linear equations can be graphed using slope, x- and y-intercepts, and/or transformations of the parent function.
· The slope of a line represents a constant rate of change in the dependent variable when the independent variable changes by a constant amount.
· The equation of a line defines the relationship between two variables.
· The graph of a line represents the set of points that satisfies the equation of a line.
· A line can be represented by its graph or by an equation. Students should have experiences writing equations of lines in various forms, including standard form, slope-intercept form, or point-slope form.
· Parallel lines have equal slopes.
· The product of the slopes of perpendicular lines is -1 unless one of the lines has an undefined slope.· Slope can be described as a rate of change and will be positive, negative, zero, or undefined.
The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to
a linear equation in two variables, including those that arise from a variety
of practical situations.
