1. 2.1 Linear Equations in Two Variables 1)Look at this power point 2)Do the “Try these” examples, you have the answers at the bottom of the page 3)Look at the videos at the end of the power point 4)Go to class ready to with the “Try these” problems worked out ready to submit 5)Be prepared to work on some new problems in class before leaving College Algebra N.DeHerrera Here is what you need to do.

2. 2.1 Linear Equations in Two Variables Objective I: Finding the slope of a line A)Find the slope of a line given an equation. Use the slope intercept form of the equation of line: y= mx + b The goal is to set up any linear equation that is given to you in this format. That way you quickly get the slope and the y-intercept. College Algebra N.DeHerrera Slope of the line y-intercept of the line (0,y)
