(-7, 2) and (5, 8)
\n" ); document.write( "Y=mX+b is the line equation where m=slope & b=the y intersection.
\n" ); document.write( "slope=(y2-y1)/(x2-x1)=(8-2)/(5-[-7])=6/12=1/2 ans.
\n" ); document.write( "Now replace the X & Y with one set of points & solve for b.
\n" ); document.write( "2=1/2(-7)+b
\n" ); document.write( "2=-7/2+b
\n" ); document.write( "b=2+7/2
\n" ); document.write( "b=2+3.5
\n" ); document.write( "b=5.5 the y intercept.
\n" ); document.write( "y=x/2+5.5
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+x%2F2+%2B5.5%29+\" (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, x/2 +5.5).
