Question -

The graph of the linear equation 2x – y= 4 cuts x-axis at
(a) (2, 0)                     
(b) (-2, 0)
(c) (0, -4)                    
(d) (0, 4)



Answer -

∵  graph of the equation,
2x – y = 4 cuts x-axis
∴ y = 0
∴  2x – 0 = 4 ⇒  2x = 4
⇒  x = 4/2 = 2
∴ The line cuts x-axis at (2, 0)               (a)
