For what value of k does the line kx+7y=10 have a slope of 3
\n" ); document.write( "The slope intercept form of a line is $\"highlight%28y=mx%2Bb%29\"$ , where m=slope.
\n" ); document.write( " $\"kx%2B7y=10\"$
\n" ); document.write( " $\"kx-kx%2B7y=-kx%2B10\"$
\n" ); document.write( " $\"7y=-kx%2B10\"$
\n" ); document.write( " $\"7y%2F7=-kx%2F7%2B10%2F7\"$
\n" ); document.write( " $\"y=%28-k%2F7%29x%2B10%2F7\"$ The slope is m=-k/7 we want it to = 3
\n" ); document.write( " $\"-k%2F7=3\"$
\n" ); document.write( " $\"-7%28-k%2F7%29=-7%283%29\"$
\n" ); document.write( " $\"highlight%28k=-21%29\"$
