ANUVRAT VIDHYALAYA (CBSE) SR SEC SCHOOL ANUVRAT VIDHYALAYA (CBSE) SR SEC SCHOOL “Sushwani Bagh”, Kalanipakkam, Pin- 635809 ACADEMIC YEAR -2016-17 TERM II - Unit test II Standard: IX Name of the Student ______________________ Subject: Maths Time : 30 Mins Marks: 20 Teacher: VS Date: 25.10.2016 SECTION – A I) Question numbers 1 to 4 carry one mark each. 1. In -2y + 3x = 14, express y in terms of x. 2.”After five years, age of mother will be 3 times the age of her son.” Represent the statement as a linear equation in two variables. 3. Find a, if linear equation 3x – ay = 6 has one solution as (4,3). 4. Find the value of K, if 2x + y = k passes through (1,1) SECTION – B II) Question numbers 5 to 7 carry two marks each. 5.Write the linear equation 5y + 6 – 2x =9 in standard form and hence write the values of a, b and c. 6. Check by substituting that x=1 and y=-2 is a solution of equation 2(x + 6) – 5(y + 7) = -11. 7. If the point (2k-3, k+2) lies on the graph of equation 2x + 3y + 15 = 0, find the value of k. SECTION –C III) Question numbers 8 to 9 carry three marks each. 8. The taxi fare in a city is as follows: For the first km, the fare is Rs. 10 and for the subsequent distance, it is Rs. 8 per km. Taking the distance covered as y km and total fare as Rs. x, write a linear equation for this information. 9. Check which of the following are solutions of equations x -2y =4 and which are not: a. (0,2) b.(2, 0) c.(4,0) “Sushwani Bagh”, Kalanipakkam, Pin- 635809 ACADEMIC YEAR -2016-17 TERM II - Unit test II Standard: IX Name of the Student ______________________ Subject: Maths Time : 30 Mins Marks: 20 Teacher: SV Date: 25.10.2016 SECTION – A I) Question numbers 1 to 4 carry one mark each. 1.
