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):

   $\left(0, −4\right)$

3. Graph the line.

• Hint (c):

  Plot the $y$-intercept and then use the slope (the numerator is the change in the $y$-value and the denominator is the change in the $x$-value) 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).
