document.write( "Question 247823: Please help with the following equation:
\n" ); document.write( "Write an equation of the line containing the specified point and parallel to the indicated line (3,-4), 5x-6y=4 I think I need to plug the points 3 and -4 in for x and y and solve but I am confused how to remove them both from the same side of the equation. Thank you for any help!

You can put this solution on YOUR website!
plug them in and you get
\n" ); document.write( "5(x)-6(y)=4
\n" ); document.write( "x=3
\n" ); document.write( "y=-4
\n" ); document.write( "5(3)-6(-4)=4
\n" ); document.write( "15+24=4
\n" ); document.write( "39=4
\n" ); document.write( "but 39 doesn't equal 4
\n" ); document.write( "That tells use that the point is not on that line.
\n" ); document.write( "But the problem already told us that.
\n" ); document.write( "The equation 5x-6y=4 is another line.
\n" ); document.write( "We want one that is parallel to that line.
\n" ); document.write( "and goes through the point(3,-4) where x=3 and y=-4\r
\n" ); document.write( "\n" ); document.write( "solve for y
\n" ); document.write( "5x-6y=4
\n" ); document.write( "5x=6y+4
\n" ); document.write( "subtract 4 from both sides
\n" ); document.write( "5x-4=y
\n" ); document.write( "y=5x-4
\n" ); document.write( "y=mx+b
\n" ); document.write( "m is the slope and b is the y intercept
\n" ); document.write( "which means that if x=0 then y is b
\n" ); document.write( "so 5 is the slope and it goes through (0,-4)
\n" ); document.write( "so we want a line of the same slope but goes through (3,-4)
\n" ); document.write( "we see that x is three more than (0,-4)
\n" ); document.write( "y=mx+b
\n" ); document.write( "we know x,y and m
\n" ); document.write( "-4=5(3)+b
\n" ); document.write( "-4=15+b
\n" ); document.write( "subtract 15 from both sides
\n" ); document.write( "-19=b
\n" ); document.write( "so now we can make the new equation
\n" ); document.write( "y=mx+b where m=5 and b=-19
\n" ); document.write( "y=5x-19 is a line parallel to the given line and goes through (3,-4)
\n" ); document.write( "and has the y intercept (0,-19)\r
\n" ); document.write( "
