+y+%2B+%281%2F2%29%2Ax+=+0+
Express in terms of +y+ which
is the slope-intercept form
---------------------------------
+y+=+-%281%2F2%29%2Ax+
This is in the form:
+y+=+m%2Ax+%2B+b+ where +b=0+
+m+=+-1%2F2+ is the slope
----------------------------------
The y-intercept is +b+=+0+
The x-value of the y-intercept
is +x+=+0+ by definition, so
the y-intercept is at ( 0,0 ) which is
the origin
------------------------------------
