To find the x- intercept, we set y=0 and solve for x:
0=.5x−3
3=.5x
6=x

So. the x-intercept is (6,0)

To find the y-intercept, it's a similar system We set x=0 and solve for y this time.
y=.5⋅0−3
y=−3
That was easy :)

So, our y-intercept is (0,−3)

Just to double check our work, let's graph the equation and see the x and y intercepts

graph{y=.5x-3}

Yep, (6,0) and (0,−3). We were right!
