Equations for proportional relationships.

Ratios and Proportional Relationships 6.RP.A.3 — Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. If the relationship is proportional, all the points plotted from your table should fall on a straight line passing through the origin \((0,0)\). Use a ruler to draw a straight line. Step 6: Find the Slope. The slope of the line in a proportional relationship is the constant of proportionality. Ratios and Proportional Relationships 6.RP.A.3 — Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. When two quantities x and y are in a proportional relationship, we can write the equation y = kx and say, “ y is proportional to x .”. In this case, the number k is the corresponding constant of proportionality. We can also write the equation x = 1 ky and say, “ x is proportional to y .”.3.2 Digging Deeper into Proportional Relationship • Represent proportional relationships as equations. • Deepen understanding of the meaning of specific ordered pairs and unit rates in representations of proportional relationships. 3 2 1 0 3 2 1 0 10 3.3 Equations and Problems
