**Mississippi College & Career Readiness Education Standards**. A function is a rule that is performed on a number, called an input, to produce a result called an output. The rule consists of one or more mathematical operations that are performed on the input. An example of a function is y = 2x + 3, where x is the input and y is the output. The operations of multiplication and addition are performed on the input, x, to produce the output, y. By substituting a number for x, an output can be determined. Read More...

MS.7. Grade 7

7.RP. Ratios and Proportional Relationships (RP)

Analyze proportional relationships and use them to solve real-world and mathematical problems

7.RP.2. Recognize and represent proportional relationships between quantities.

7.RP.2.b. Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.

MS.CM7. Compacted Mathematics Grade 7

CM7.RP. Ratios and Proportional Relationships

Analyze proportional relationships and use them to solve real-world and mathematical problems

7.RP.2. Recognize and represent proportional relationships between quantities.

7.RP.2.b. Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.

CM7.EE. Expressions and Equations

Understand the connections between proportional relationships, lines, and linear equations

8.EE.5. Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.

8.EE.6. Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.
