Help me determine the slope of the graph of the linear function $\"f\"$ , given: $\"f%283%29=-1\"$ , $\"f%28-5%29=-1\"$ \r
\n" ); document.write( "\n" ); document.write( "equation of a line is:
\n" ); document.write( " $\"f%28x%29=mx%2Bb\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"f%283%29=-1\"$ means if $\"x=3\"$ that $\"f%28x%29=-1\"$ , and that is a point ( $\"3\"$ , $\"-1\"$ )
\n" ); document.write( " $\"f%28-5%29=-1\"$ -> that is a point ( $\"-5\"$ , $\"-1\"$ )
\n" ); document.write( "as you can see, both points have same $\"f%28x%29\"$ value
\n" ); document.write( "if so, slope $\"+m=0\"$ , and if a slope is $\"0\"$ , we have a $\"horizontal\"$ line; $\"f%28x%29=a\"$ \r
\n" ); document.write( "\n" ); document.write( "and, your line is
\n" ); document.write( " $\"f%28x%29=-1\"$ \r
