Write your answers according to the instructions given below with the questions. 3. Begin each section on a new page. S E CT I O N - A Given below are 1 to 15 multiple choice questions. Each carries one mark. Write the serial number ( a or b or c or d ) in your answer book of the alternative which you feel is the correct answer of the question. 1. If the co-ordinates of a point ( 6, - 1 ) changes to ( 8, - 4 ), then write the co-ordinates of the point where the origin is shifted. 3. 2. Write the measure of the angle between the lines x + y = 0 and y = [ π ] ( a ) 4 π ( b ) 3 π ( c ) 2 π ( d ) 0 Solution : Slope of the line x + y = 0 is m = - 1. y = [ π ] is a horizontal line. Angle between the horizontal line and the line of slope m is tan - 1 l m l = tan - 1 l - 1 l = 4 π .
