Lesson 06: More Linear Relationships | Unit 3: Linear Relationships

Explain what the slope and $$y$$ -intercept mean in the situation where a graph represents the perimeter, $$y$$ , in units, for an equilateral triangle with side length $$x$$ units. The slope of the line is 3 and the $$y$$ -intercept is 0.

Explain what the slope and $$y$$ -intercept mean in the situation where the amount of money, $$y$$ , in a cash box after $$x$$ tickets are purchased for carnival games. The slope of the line is $$\frac14$$ and the $$y$$ -intercept is 8.

Explain what the slope and y-intercept mean in the situation where the number of chapters read, y, after x days. The slope of the line is 5/4 and the y-intercept is 2.

Explain what the slope and y-intercept mean in the situation where the graph shows the cost in dollars, y, of a muffin delivery and the number of muffins, x, ordered. The slope of the line is 2 and the y-intercept is 3.
