You can put this solution on YOUR website!
The answer is B.\r
\n" ); document.write( "\n" ); document.write( "Here is how we may solve it:\r
\n" ); document.write( "\n" ); document.write( "8x -9y =1
\n" ); document.write( "First, you must isolate the y variable in order to determine the slope
\n" ); document.write( "y = 8/9x + 1
\n" ); document.write( "Now, we know that the slope of the line is 8/9, and since we know that parallel lines share equal slopes, 8/9 must be the slope for the line which we are solving for.
\n" ); document.write( "Plug the point (7 , 3) into the point slope formula using the slope which we just found.
\n" ); document.write( "This gives us
\n" ); document.write( "y - 3 = 8/9(x - 7)\r
\n" ); document.write( "\n" ); document.write( "Multiply negetive seven by 8/9 to get -56/9 and add a positive 27/9. This gives us -29/9 for the y-intercept,
\n" ); document.write( "Thus,
\n" ); document.write( "y = 8/9x - 29/9
\n" ); document.write( "
\n" );
