Solving for y

50 Minute Class, Algebra 1, Curriculum

Learning Goal: Understand how to rearrange linear functions into slope-intercept form, and determine the slope of these equations.


Activity:

Classwork:

Focus on determining the slope and y-intercept of the different forms. Show how solving for y allows us to see that.
