i have a problem that says solve for k where the equation is 4x-ky-7=0 and the slope is = to 3. How do I solve for k?\r
\n" ); document.write( "\n" ); document.write( "4x-ky-7=0 (the equation of a line is y=mx+b where m is the slope and b is the y-intercept (or vertical intercept or point (0,b)))
\n" ); document.write( "-ky = -4x + 7
\n" ); document.write( " ky = 4x - 7
\n" ); document.write( " y = 4/k * x - 7/k
\n" ); document.write( "said the slope = 3, so m=3 and m=4/k and 4/k = 3
\n" ); document.write( "4/k = 3 (multiply both sides by k)
\n" ); document.write( "4 = 3k
\n" ); document.write( "4/3 = k\r
\n" ); document.write( "\n" ); document.write( "b= -7/k = -7/(4/3)
\n" ); document.write( "(4/3)b = -7
\n" ); document.write( "4b = -21
\n" ); document.write( "b = -21/4\r
\n" ); document.write( "\n" ); document.write( "y = 3x - 21/4\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
