13 min video shows how to graph from a table and/or using an equation. Also discussed various types of slopes.
Slope and Proportional Relationships is a free educational video by ElaineandTomDorlis.It helps students in grades 8th practice the following standards 8.EE.B.6,8.EE.B.5,.
1. 8.EE.B.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..
2. 8.EE.B.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..
