You can put this solution on YOUR website!
y=mx+b [Slope-intercept equation of a line]
\n" ); document.write( "m=(y-y2)/(x-x2) [Formula for the slope of a line]
\n" ); document.write( "(1,6),(3,0) [Coordinate points]
\n" ); document.write( ".
\n" ); document.write( "m=(0-6)/(3-1)=-6/2=-3
\n" ); document.write( ".
\n" ); document.write( "y=mx+b [plug-in the values of one point and the slope]
\n" ); document.write( "0=(-3)(3)+b [Solve for b]
\n" ); document.write( "0=-9+b
\n" ); document.write( "9=b
\n" ); document.write( ".
\n" ); document.write( "y=-3x+9 [Plug-in the values of the slope and y-intercept for the slope-intercept form of the line.]
\n" ); document.write( ".
\n" ); document.write( "Check by pluggin in the values for the second points.
\n" ); document.write( "(1, 6)
\n" ); document.write( "6=-3(1)+9
\n" ); document.write( "6=-3+9
\n" ); document.write( "6=6 [Checks out]\r
