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?
Answered by MathMate
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?
Answered by barb
is it (0,0)? I thought x was the slope
Answered by MathMate
m is the slope, and <b>b</b> is the y-intercept in y=mx+b. The given equation can be converted to the form
y=(1/2)x + <b>0</b>
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.
Answered by barb
the question tells us to type in an ordered pair
Answered by MathMate
In that case, you could answer with the ordered pair of the intersection point, namely (0,0) as you mentioned.
