Fine the value of r so the line that passes through each pair of points has the given slope.\r
\n" ); document.write( "\n" ); document.write( "(-4,3), (r,5), m=1/4
\n" ); document.write( "The slope formula is \"highlight%28m=%28y2-y1%29%2F%28x2-x1%29%29\"
\n" ); document.write( "m=1/4, (x1,y1)=(-4,3) and (x2,y2)=(r,5)
\n" ); document.write( "\"1%2F4=%285-3%29%2F%28r-%28-4%29%29\"
\n" ); document.write( "\"1%2F4=2%2F%28r%2B4%29\" Cross multiply.
\n" ); document.write( "\"1%2A%28r%2B4%29=2%284%29\"
\n" ); document.write( "\"r%2B4=8\"
\n" ); document.write( "\"r%2B4-4=8-4\"
\n" ); document.write( "\"highlight%28r=4%29\"
