In this lesson we will learn how to determine the y-intercept of a line
if you have been given the graph of the line.
The y-intercept of a line is the y-coordinate
of the point at which the line intersects the y-axis.

Look at the diagram below.....
As you can see, the line drawn on the
coordinate plane clearly intersects the y-axis
at the point (0,1).
Since the y-coordinate of that point is "1"
the y-intercept of the line is "1".

Pretty easy right?
Just to be sure...let's look at one more example:

Remember, if you have been given the graph of a line,
the y-intercept is the y-coordinate of the point
at which the line crosses the y-axis...
It's that easy!
