y-intercept is a point where the graph of a function intersects with the y-axis
y-intercept is value of y where x=0
y= -1/2x
Slope -1/2
y-intercept y= -1/2*0= -1/0= +/- infinity
y= 3x-4
Slope 3
y-intercept y=3*0-4=0-4= -4
I'm confused on two questions that are kind of similiar:
State the slope and y-intercept of
y= -1/2x
I know the slope is -1/2 but I don't know the y-intercept
State the slope and y-intercept of
y= 3x-4
I know the slope is 3, but I don't know if the y-intercept is 4 or -4.

If yor function:
y= -1/2x
mean y=(-1/2)*x
then:
Slope -1/2
y-intercept y=(-1/2)*0= 0
y= -1/2x
mean y=(-1/2)*x
then:
Slope -1/2
y-intercept y=(-1/2)*0= 0
