 PQ is a straight line of 13 units. If P has the coordinates (5,3) and Q has the coordinates (7,y); find the values of'y'

question no 202
 (PLEASE EXPLAIN THE CALCULATIONS STEP BY STEP). Find the point on the yaxis whose distance from the points A(6,7) and B(4,3) are in the ratio 1:2.
 The centre of a circle is (2x1,3x+1). Find x if the circle passes through (3,1) and the length of its diameter is 20 unit. (PLEASE EXPLAIN THE CALCULATIONS STEP BY STEP . I HAVE A DOUBT IN SOLVING THE QUADRATIC EQUATION )
