Intercept
Another important property of a line (or any curve on a coordinate plane) are its x- and y-intercepts: the points where the line intersects coordinate axes. Watch this lecture series and complete the interactive exercises.

1.
The 
-intercept is the point where the graph intersects the -axis. Since the -axis is also the line 
, the 
-value of this point will always be 
.
