You can put this solution on YOUR website!
you have 2 sets of points (0,0) & (2,3) thus the slope is
\n" ); document.write( "(y2-y1)/(x2-x1)
\n" ); document.write( "(3-0)/2-0)
\n" ); document.write( "3/2 is the slope.
\n" ); document.write( "now supstitute one set of points & solve for the y intercept
\n" ); document.write( "3=3/2*2+b
\n" ); document.write( "3=3+b
\n" ); document.write( "b=3-3
\n" ); document.write( "b=0 which is the y intercept
\n" ); document.write( "y=3x/2
\n" ); document.write( " $\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+3x%2F2%29+\"$ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, y = 3x/2).
