Grade 8 - Patterns and Relations

Standard 8.PR.1 - Graph a function of a proportional relationship on a coordinate graph.

Included Skills:

Demonstrate understanding of linear relations concretely, pictorially (including graphs), physically, and symbolically.
• Analyze and describe the relationship shown on a graph for a given situation (e.g., "The graph is showing that, as the temperature rises, the number of people in the mall decreases").
• Explain how a given linear relation is represented by a given table of values.
• Model a linear relation shown as an equation, a graph, a table of values, or a concrete or pictorial representation in one or more other forms.
• Analyze a set of equations, graphs, ordered pairs, and tables of values, sort the set according to representing the same linear relations, and explain the reasoning.
• Determine the missing coordinate of an ordered pair given the equation of a linear relation, a table of values, or a graph and explain the reasoning.
• Determine which of a set of graphs, equations, tables of values, sets of ordered pairs, and concrete or pictorial representations represent a linear relationship and justify the reasoning.
• Determine if an ordered pair satisfies a linear relation given as a table of values, concrete or pictorial representation, graph, or equation and explain the reasoning.
• Identify situations relevant to self, family, or community that appear to define linear relations and determine, with justification, whether the graph for the situation would be shown with a solid line or not.
