# Standards Addressed

- The motion of an object can be described by its position, direction of motion, and speed. That motion can be
measured and represented on a graph. (NSES p154, grades 5-8)
- Graphs can show a variety of possible relationships between two variables. (BSL 9B/M3, grades 6-8)
- Tables, graphs, and symbols are alternative ways of representing data and relationships that can be translated
from one to another. (BSL 9B/H4, grades 9-12)
- 8.F.3. Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line.
- 8.F.4. Construct a function to model a linear relationship between two quantities. Determine the rate of
change and initial value of the function from a description of a relationship or from two (x, y) values,
including reading these from a table or from a graph. Interpret the rate of change and initial value of a
linear function in terms of the situation it models, and in terms of its graph or a table of values.
- 8.F.5. Describe qualitatively the functional relationship between two quantities by analyzing a graph
