\n" ); document.write( "You wrote: \"Find All points having an x-coordinate of 9 distance from the point is (3,-2) is 10\"
\n" ); document.write( "Try, perhaps: \"Find all points having an x-coordinate of 9, if the distance from the point (3,-2) is 10\"
\n" ); document.write( "You want the distance from (3,2) to (9,y) to be 10.
\n" ); document.write( "You can use the distance formula (aka the Pythagorean Theorem) to solve the problem; but it's not needed.
\n" ); document.write( "The difference in the x coordinates is 6 and the distance is 10; that means you have a right triangle with one leg 6 and hypotenuse 10. That makes the other leg 8. (it is a multiple of the simplest Pythagorean triple, 3-4-5).
\n" ); document.write( "So the two y values are 8 more or less than the y value of the given point.
\n" ); document.write( "(1) 2+8 = 10
\n" ); document.write( "(2) 2-8 = -6
\n" ); document.write( "ANSWERS: (9,10) and (9,-6) \n" ); document.write( "
