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?

The slope-intercept form of a line is
where m is the slope and b is the y-intercept.
You can consider the given equation as:
So what is the y-intercept?

is it (0,0)? I thought x was the slope
- math - MathMate, Sunday, August 22, 2010 at 9:52pm
m is the slope, and b is the y-intercept in y=mx+b. The given equation can be converted to the form
y=(1/2)x + 0
So what is the y-intercept for the given equation?
Note: the y-intercept is a single numerical which represents the y-coordinate of the intersection of the line with the y-axis. It is not a coordinate pair.

the question tells us to type in an ordered pair

In that case, you could answer with the ordered pair of the intersection point, namely (0,0) as you mentioned.
