Solving Slope-Intercept Form Word Problems

The video tutorial by Mr. C introduces the concept of slope intercept form using a visual pattern of cubes. It explains how to derive the equation y = mx + b, where m is the slope and b is the y-intercept. The tutorial includes examples such as calculating the cost of internet service and gym membership, and modeling a plane's altitude change. It also covers graphing the equation and emphasizes understanding the slope as the rate of change and the y-intercept as the initial value.
