If $y=\frac{1}{2}x−4$:

1. What is the slope of the line?

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

$\frac { 1 } { 2 }$

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

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

$\left(0, −4\right)$

3. Graph the line.

• 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).

Use the eTool below to graph the line and determine the slope and $y$-intercept.
