Question 468447
<font face="Times New Roman" size="+2">


You cannot determine the slope using <i>only</i> the *[tex \Large y]-intercept, or by using any other single point for that matter.  You need two points to uniquely determine a line.


Consider the equation *[tex \Large y\ =\ ax] where *[tex \Large a] is any real number. The graph is a line passing through the origin with a slope of *[tex \Large a].  The *[tex \Large y]-intercept is the origin, but the slope is *[tex \Large a] and since *[tex \Large a] is any real number, there are an infinite number of lines with the the specified *[tex \Large y]-intercept all with different slopes.

My calculator said it, I believe it, that settles it
