Use two-dimensional coordinate geometry.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x^2+y^2=12^2 the circle, and you have a possible coordinate x=10 and x=-10; what is the value of y for either of these coordinates? The midpoint of the chord will be on the positive y-axis.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Draw the graph.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "You can find your result algebraically letting x=10, and solve the circle equation for y. \n" ); document.write( " |
