On graph paper, graph the line that goes through the points $\left(–6, 3\right)$ and $\left(–3, –1\right)$.  

1. What is the slope of the line?

   Hint (a):

   Draw a slope triangle to calculate the change in $y$ over the change in $x$.

   Answer (a):

   $-\frac{4}{3}$

2. What is the $y$-intercept?

   Hint (b):

   At what point does the line cross the $y$-axis?

   Answer (b):

   $\left(0, −5\right)$

3. Find the equation of the line.

   Hint (c):

   Remember $y=mx+b$.
