(2,4) and( 3,5)
\n" ); document.write( "First we find the slope.
\n" ); document.write( "slope=(5-4)/(3-2)=1
\n" ); document.write( "Y=mX+b
\n" ); document.write( "4=1*2+b
\n" ); document.write( "4=2+b
\n" ); document.write( "b=4-2
\n" ); document.write( "b=2 the Y intercept.
\n" ); document.write( "y=x+2 is the line equation with a slope=1, a Y intercept=2 thru (2,4) & (3,5).
