Q. 1

# 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 =12(ii) x- -5 =0(iii) 2x+3y= (iv) 3x = -7y(v) 2x+3 = 0(vi) y – 5 = 0(vii) 4=3x(viii) y= (i) -2x+3y =12

-2x + 3y – 12 = 0

a = - 2, b = 3, c = -12

(ii) x- -5 =0

2x – y – 10 = 0

a = 2, b = -1, c = -10

(iii) 2x+3y= 2x + 3y – = 0

a = 2, b = 3, c = (iv) 3x = -7y

3x + 7y = 0

a = 3, b = 7 and c = 0

(v) 2x+3 = 0

a = 2, b = 0 and c = 3

(vi) y – 5 = 0

a = 0, b = 1, c = - 5

(vii) 4 = 3x

3x – 4 = 0

a = 3, b = 0, c = -4

(viii) y = x/2

x – 2y = 0

a = 1, b = -2, c = 0
