If $y=\frac{1}{2}x−4$: 2-49 HW eTool (Desmos) Homework Help ✎

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.

(0, −4)

3. Graph the line.

• Plot the $y$-intercept 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).

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