I'm confused on two questions that are kind of similiar:
State the slope and yintercept of
y= 1/2x
I know the slope is 1/2 but I don't know the yintercept
State the slope and yintercept of
y= 3x4
I know the slope is 3, but I don't know if the yintercept is 4 or 4.

yintercept is a point where the graph of a function intersects with the yaxis
yintercept is value of y where x=0
y= 1/2x
Slope 1/2
yintercept y= 1/2*0= 1/0= +/ infinity
y= 3x4
Slope 3
yintercept y=3*04=04= 4 
If yor function:
y= 1/2x
mean y=(1/2)*x
then:
Slope 1/2
yintercept y=(1/2)*0= 0
