If $y=\frac{1}{2}x−4$:  

1. What is the slope of the line?

   Hint (a):

   In the equation of a line, $y=mx+b,m=$ slope.

   Answer (a):

   $\frac{1}{2}$

2. What is the $y$-intercept of the line?

   Hint (b):

   In the equation of the line, $y=mx+b,b=y$-intercept.

   Answer (b):

   $(0,−4)$

3. Graph the line.

• Hint (c):

  Plot the $y$-intercept point and then use the slope (the top value is $y$ and the bottom one is $x$) to find another point, and draw a line connecting the points. You should be able to draw a slope triangle on your graph that matches the slope you found in part (a).
