Review what you know about graphs by answering the following questions.   

1. What is the equation of the line graphed at right?

   Hint (a):

   Use the $y$-intercept and the slope to write an equation of the line in the form of $y = mx + b$. (Create a slope triangle if you need one).

2. What are its $x$- and $y$-intercepts?

• Hint (b):

  Remember that the $x$-intercept is the point on the graph where $y = 0$ and that the $y$-intercept is the point where $x = 0$.
