\n" ); document.write( "(3,4) (5,7) and I know how ti work out the problem, I just can't set it up! I true m= 4-7 over 3-5 but then I got stuck and knew it wasn't right. What do I do? \n" ); document.write( "

(3,4),(5,7)
\n" ); document.write( "slope = $\"+%28+7+-+4+%29+%2F+%28+5+-+3+%29+=+3%2F2+\"$
\n" ); document.write( "So far I have:
\n" ); document.write( " $\"+y+=+%283%2F2%29%2Ax+%2B+b+\"$
\n" ); document.write( "Now I can plug one of the given points back into equation
\n" ); document.write( " $\"+4+=+%283%2F2%29%2A3+%2B+b+\"$
\n" ); document.write( " $\"+4+=+9%2F2+%2B+b+\"$
\n" ); document.write( " $\"+b+=+8%2F2+-+9%2F2+\"$
\n" ); document.write( " $\"+b+=+-1%2F2+\"$
\n" ); document.write( "The equation is
\n" ); document.write( " $\"+y+=+%283%2F2%29%2Ax+-1%2F2+\"$
\n" ); document.write( "check:
\n" ); document.write( "Does it go through (5,7)?
\n" ); document.write( " $\"+y+=+%283%2F2%29%2Ax+-1%2F2+\"$
\n" ); document.write( " $\"+7+=+%283%2F2%29%2A5+-1%2F2+\"$
