Question

Describe the graph of a linear equation of Ax+By=C for which a)A=0

Answer 1

$a)\ A=0\\\\then\ Ax+By=C\Rightarrow By=C\to y=\frac{C}{B}\\\\picture\ \#1$


$b)\ B=0\\\\then\ Ax+By=C\Rightarrow Ax=C\to x=\frac{C}{A}\\\\picture\ \#2$


$c)\ C=0\\\\then\ Ax+By=C\Rightarrow Ax+By=0\to By=-Ax\to y=-\frac{A}{B}x\\\\picture\ \#3$
