Slide Content
1. ### Slide 1 - Unit 3 Lesson 12: Linear Equations and Slope

• Springboard lesson 11.1
2. ### Slide 2 - Learning Outcomes

• Understand the concept of slope as a ratio between any two points on a line
• Graph proportional relationships; interpret the slope and the y-intercept (0,0) of the graph

• C = 30d

8. ### Slide 9 - Definitions

• Vertical change: the number of spaces moved up or down on a graph. “up” movement is represented by a positive number, “down” is represented by a negative number.
• Horizontal Change: the number of spaces moved right or left on a graph. Movement to the right is indicated by a positive number. Movement to the left is indicated by a negative number.

• = =

12. ### Slide 15 - Slope

• Look back at the equation we wrote at the very beginning of the lesson for the High Ratio Mountain, can you find this ratio of in that equation?
• C = 30d
13. ### Slide 16 - Slope

• This idea of a common ratio on a line is called the slope of a line
• vertical change to horizontal change
• can also be written as
• also known as the constant rate of change
• All linear relationships have a constant rate of change, or slope
• the y-intercept of a line is the point at which the line crosses the y-axis.
• Y-intercept
