How to Write & Graph Direct Variation Equations | 7.RP.A.2 💚

In this video lesson we will continue our learning about graphs of proportional relationships. We will learn that the graph of a line that is a proportional relationship can be written as a direct variation in the form y=kx where k cannot be zero and represents the constant of proportionality. We will learn how to classify an equation as a direct variation. We will learn that a direct variation equation must have an x and a y variable term where the exponent is 1, the "invisible" one. We will learn how to solve for y to determine if an equation is a direct variation. We will learn how to write a graphed proportional relationship as an equation in the form y=kx. We will also learn how to graph the equation y=kx using a table. We will also learn how to graph the equation in the form y=kx using the constant of proportionality k. We will also identify the constant of proportionality from an equation. Student practice is embedded in the lesson with modeled exemplar solutions. #directvariation #graphy=kx #writeanequation https://www.teacherspayteachers.com/S... 00:00 Introduction 00:47 Equation of a Proportional Relationship 01:38 Direct Variation - What is it? 04:06 How to Identify a Direct Variation 07:00 Student Practice #1 08:33 How to Write an Equation 10:09 Student Practice #2 11:17 Graph an Equation with a Table 13:48 Student Practice #3 14:54 Graph an Equation Using Constant of Proportionality 16:40 Student Practice #4 CCSS.MATH.CONTENT.7.RP.A.2.B Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.
