Exploring Linear Relationships

The video tutorial covers the concept of slope-intercept form, explaining its components: slope and y-intercept. It then applies this knowledge to compare different scenarios, including the speeds of runners, travel rates of families, savings rates, and skydiving descent rates. Each example uses slope to determine which subject is faster or more efficient in their respective context.

In the slope-intercept form equation y = mx + b, what does 'm' represent?

• The constant term

• The y-intercept

• The slope or rate of change

• The x-intercept
