EXERCISE 4.1

NCERT class 9 maths chapter 4 Linear Equations in Two Variables

Question 1:The cost of a notebook is twice the cost of a pen. Write a linear equation in two variables to represent this statement. (Take the cost of a notebook to be  x and that of a pen to be  y).

Question 2:Express the following linear equations in the form ax + by + c = 0 and indicate the values of a, b and c in each case: (i) 2x + 3y = 9.35 (ii) x – 5 y – 10 = 0 (iii) –2x + 3y = 6 (iv) x = 3y (v) 2x = –5y (vi) 3x + 2 = 0 (vii) y – 2 = 0 (viii) 5 = 2x
