Question

Draw the graph of the following linear equations in two variable : 2𝑦 = −𝑥 + 1

Answer 1

we have 

`2y = -x + 1`

⇒ x -1 = 2y          ............. (1)

Putting  y = 0 , we get   x = 1 - 2 × 0 = 1 

Putting  y = -1 , we get  x = 1 - 2 ( - 1) = 3

Thus, we have the following table giving the two points on the line represented by
the equation 

2y = x - 3 

2y = - x + 1

Graph for the equation 2y = - x +1
