The slope-intercept form of a line is

y=mx+b

where m is the slope and b is the y-intercept.

You can consider the given equation as:

y=(1/2)x+0

So what is the y-intercept?

is it (0,0)? I thought x was the slope

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.
