The video tutorial covers solving word problems using slope-intercept form. It begins with an introduction to word problems and moves on to solving a problem involving Marty's spending. The tutorial then addresses a UPS shipping charge problem, followed by creating an equation for yoga lesson costs. It also includes a problem about purchasing hamburger and chicken, demonstrating how to write and convert equations between standard and slope-intercept forms. Finally, the video explains linear estimation using a population prediction model.

What is the equation in standard form for buying hamburger and chicken with 60 dollars?

• 1.5x + 2.5y = 60

• 1.5x + 2.5y = 24

• 1.5x + 2.5y = 0

• 0.6x + 24y = 60

What is the slope-intercept form of the equation 1.5x + 2.5y = 60?

• y = 0.6x + 24

• y = 1.5x + 60

• y = -1.5x + 60

• y = -0.6x + 24
