graph the equation and identify the y intercept: y=1/2x
How do work this can anyone help with step by step as i will have more of these?

• math -

Do you perhaps mean
y = (1/2) x
?
If so, when x = 0, y = 0

If it is really
y = 1/(2x)
then when x = 0, y is undefined.

• math -

it really means y= 1/2 x
Does x have to represent 0? I need to know why

• math -

The y axis intercept is the value of y when x = 0

• math -

because any old function that crosses the y axis does so along the vertical line x = 0

This one never quite hits the vertical axis

• math -

the question says to list the ordered pair,is the ordered pair (0,0).Some of the questions give "undefined as an option, but not this question.

• math -

Well, 1/(2*0) is undefined
so I would have to say
(0, oo)
and
(0, -oo)

where oo means infinity.

Are you absolutely sure you do not have a typo in the problem statement?
If it were y = x/2 the solution would be (0,0)

• math -

Graph the equation and identify the y intercept: y= one half*x or 1/2*x
The y intercept is____
type in the ordered pair.

That is the exact question
