Find an equation of the line that has the same y-intercept as the line x - 3y = 6 and contains the point (5,-1).
\n" ); document.write( "-----------------
\n" ); document.write( "x-3y = 6
\n" ); document.write( "The y-intercept is (0,2).
\n" ); document.write( "--------------------
\n" ); document.write( "Find the eqn thru the 2 points:
\n" ); document.write( "Do it like this:
\n" ); document.write( "-----------------------
\n" ); document.write( " Given 2 points example.
\n" ); document.write( "Find the equation of the line thru the points (2,1) and (3,5)
\n" ); document.write( "---------------------
\n" ); document.write( "This is a 2 step process. First find the slope of the line thru the points.
\n" ); document.write( "slope, m = diffy/diffx
\n" ); document.write( "m = (5-1)/(3-2)
\n" ); document.write( "m = 4
\n" ); document.write( "---------
\n" ); document.write( "Now use y = mx + b with either point to find b, the y-intercept.
\n" ); document.write( "y = mx + b
\n" ); document.write( "5 = 4*3 + b
\n" ); document.write( "b = -7
\n" ); document.write( "-------
\n" ); document.write( "y = mx + b
\n" ); document.write( "y = 4x - 7 is the answer.
