Lesson 4: Slope-Intercept Form
Duration of Days: 4
Lesson Objective
Students create and use the equation y=mx+b for a line.
Students will identify the y-intercept as "b".
What does y-intercept represent in a real-world scenario?
How can you write a linear equation to represent a real-world situation?
slope-intercept form
y-intercept
slope
coefficient
constant
8.EE.B.6: 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.
Students will derive and apply the slope-intercept form (y = mx + b) of a linear equation, identify and interpret the slope (m) and y-intercept (b) from various mathematical and real-world representations. (DOK 2)
