1.) When A=0,A=0, there is no x-intercept. Complete the sentence to show how you know this.
The graph of By=CBy=C is a_____line, so it doesn't cross the ______unless y=0y=0 and it is the x-axis.

2.) When B=0,B=0, there is no y-intercept. Complete the sentence to show how you know this.
The graph of Ax=CAx=C is a______line, so it doesn't cross the ______unless x=0x=0 and it is the y-axis.

3.) When C=0,C=0, the x-intercept and the y-intercept both occur at the origin. Complete the sentence to show how you know this.
If x=0x=0 in Ax+By=0Ax+By=0 and AA and BB are nonzero, then y=y= ______ .
If y=0y=0 in Ax+By=0Ax+By=0 and AA and BB are nonzero, then x=x= _______.
Therefore, the origin indicates the______.
