Draw the graph of the equation y = 1 2 x .

When we are required to draw a sloping line, we use a table of values. We shall choose x = 0 , x = 1 , x = 2 . When x = 0 ⇒ y = 1 2 × 0 ⇒ y = 0 . x = 1 ⇒ y = 1 2 × 1 ⇒ y = 1 2 . x = 2 ⇒ y = . 1 2 × 2 ⇒ y = 1 . The table is as follows: x 0 1 2 y 0 1 2 1 We shall now plot the points A ( 0 , 0 ) , B 1 , 1 2 , C 2 , 1 and join them up with a straight line P Q ↔ . Thus, we get, the line P Q ↔ as the graph for the equation y = 1 2 x .
