You can put this solution on YOUR website!
3x-y=4,,,,obviously,,,3x-4=y,,,from y=mx+b,,,,m=3
\n" ); document.write( ".
\n" ); document.write( "to find slope without this, try evaluating two points on graph
\n" ); document.write( ".
\n" ); document.write( "when x=0,,y=-4,,,,,,,when x=1,,,,y=-1
\n" ); document.write( ".
\n" ); document.write( "now,,,,m=(y2-y1)/(x2-x1) ={-4-(-1)}/{0-1} = -3/-1 = 3,,,,,,as above
\n" ); document.write( ".
\n" ); document.write( "Remember the slope is rise over run, and we only have to review numerator if denominator is +1.,,,,,,,,(-1-(-4)) =3
\n" ); document.write( ".
\n" ); document.write( "When there are negatives, however, it is best to use full formula
\n" ); document.write( ".
