The slope of the line $y = 1/2x -4$ is $1/2$ , the y-intercept is $-4$ , and the x-intercept is $8$ .

When a linear equation is in the form $y = mx + b$ , the slope is $m$ . In this case, the slope is the coefficient of $x$ which is $1/2$ .

To find the y-intercept, substitute $0$ for $x$ :
$y = 1/2*0 -4$
$y = -4$
The y-intercept is $-4$ .

To find the x-intercept, substitute $0$ for $y$ :
$0 = 1/2x -4$
$1/2x = 4$
$x = 8$
The x-intercept is $8$ .
