Solving Slope Intercept Word Problems

The video tutorial covers solving word problems using slope-intercept form. It begins with an introduction to the concept and then applies it to various scenarios, such as calculating costs for movie snacks, fish tanks, and fish, as well as understanding ratios in a cookie recipe. The tutorial also includes practice problems and equations, and concludes with problems involving diving and tree growth. Key concepts like slope and y-intercept are emphasized throughout.

What is the formula for calculating the slope between two points?

• y1 - y2 over x1 - x2

• x1 - x2 over y1 - y2

• y2 - y1 over x2 - x1
