(-3,4), (3,-4)
\n" ); document.write( "First we find the slope (m)
\n" ); document.write( "m=(y2-y1)/(x1-x2)
\n" ); document.write( "m=(-4-4)/(3+3)
\n" ); document.write( "m=-8/6=-4/3 is the slope
\n" ); document.write( "Now replace one set of x&y values in the line formula[Y=mX+b] & solve for the y intercept(b).
\n" ); document.write( "4=-4/3*-3+b
\n" ); document.write( "4=12/3+b
\n" ); document.write( "4=4+b
\n" ); document.write( "b=4-4
\n" ); document.write( "b=0
\n" ); document.write( "y=-4x/3 is the line equation for a line through (-3,4)(3,-4).
