The linear function is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=dd6bd06c522c8dcf7267ae2d663ea823.png\")
.
Observe the function; there is no y component.
\So, line is parallel to y axis.
\Check:
\The y-intercept is the value of y when x = 0.

(Substitute 0 for x)
It is not possible. So, the graph never crosses the y - axis.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/step2.JPG\")
The x-intercept is the value of x when y = 0.

(Substitute 0 for y)
The x - intercept is 8. The graph crosses the x - axis at (8, 0).![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/step3.JPG\")
Use these ordered pairs to graph the equation.
\ \1. Draw a coordinate plane
\2. Plot the points
\3. Draw a line through these points.
