Question

Write each of the following as an equation in two variables. 

(i) 2x = - 3 

(ii) y = 3 

(iii) 5x = \(\frac{7}{2}\)

(iv) y = \(\frac{3}{2}\)x

Answer 1

(i) 2x = - 3 

⇒ 2x + 0y + 3 = 0 

(ii) y = 3 

⇒ 0x + y – 3 = 0 

(iii) 5x = 7/2 

⇒ 10x + 0y – 7 = 0 

(iv) y = \(\frac{3}{2}x\)

⇒ 3x – 2y + 0 = 0
