MCQ | Class 11 | Ch-09 STRAIGHT LINES MCQ | CHAPTER 09 | CLASS 11 STRAIGHT LINES Question 1 What is the distance between (1, 3) and (5, 6)? a) 3 units b) 4 units c) 5 units d) 25 units Answer: c Question 2 What is the distance of (5, 12) from origin? a) 6 units b) 8 units c) 10 units d) 13 units Answer: d Question 3 The locus of a point, whose abscissa and ordinate are always equal is (a) x + y + 1 = 0 (b) x – y = 0 (c) x + y = 1 (d) none of these. Answer: b Solution Hint: Let the coordinate of the variable point P is (x, y) Now, the abscissa of this point = x and its ordinate = y Given, abscissa = ordinate ⇒ x = y ⇒ x – y = 0 So, the locus of the point is x – y = 0 Question 4 Angle made by line with ____________ measured anticlockwise is called inclination of the line. a) positive x-axis b) negative x-axis c) positive y-axis d) negative y-axis Answer: a Question 5 Slope of a line is given by _________ if inclination of line is α. a) sinα b) ...
