y-intercept: (-4)
x-intercept: 8

Explanation:

The y-intercept is the value of y when x=0
Given
color(white)("XXX")y=1/2x-4
when x=0
color(white)("XXX")y=1/2(0)-4=-4

The x-intercept is the value of x when y=0
Given
color(white)("XXX")y=1/2x-4
when y=0
color(white)("XXX")0=1/2x-4

color(white)("XXX")4=1/2x

color(white)("XXX")x=8
