Week 8: September 28-October 2

Topic 2-6 “Connect Proportional Relationships and Slope”

• Standard : 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; know and apply 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.

• Objective

  1. Find the slope of a line using different strategies

  2. Interpret a slope in context and relate it to steepness on a graph

• Essential Understanding

1. Slope is a measure of the steepness of a line.  In a proportional relationship, slope is the same as the unit rate and the constant of proportionality.

• Essential Question: What is slope?

Topic 2-7 “Analyze Linear Equations:y = mx + b”

• Standard : 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; know and apply 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.

• Objective

  1. Understand how the constant of proportionality and the slope relate in a linear equation

  2. Write and graph a linear equation in the form y=mx+b

• Essential Understanding

1. The slope, constant of proportionality, and unit rate are equal for proportional relationships.

• Essential Question: How does slope relate to the equation for a proportional relationship?

Topic 2-8 “Understand the y-intercept of a line”

• Standard : 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; know and apply 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.

• Objective

  1. Interpret and extend the table or graph of a linear relationship to find its y-intercept

  2. Analyze graphs in context to determine and explain the meaning of the y-intercept

• Essential Understanding

1. The y-intercept of a line is the y-coordinate of the point where the graph of the line crosses the y-axis.  Its meaning depends on the context of the graph.

• Essential Question: What is the y-intercept and what does it indicate?
