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.

Intercepts from a table

1. This table gives a few $(x,y)$ pairs of a line in the coordinate plane.

$x$	$y$
33	-22
52	-33
71	-44

What is the $x$ -intercept of the line?

2. This table gives a few $(x,y)$ pairs of a line in the coordinate plane.

$x$	$y$
-28	-54
-21	-40
-14	-26

What is the $y$ -intercept of the line?

3. This table gives a few $(x,y)$ pairs of a line in the coordinate plane.
