Question
Draw the graph of the following linear equations in two variables: x + y = 4
✓
Answer
We have, x + y = 4 ⇒ x = 4 - y ...(i) Putting y = 0, we get x = 4 - 0 = 4 Putting y = 3, we get x = 4 - 3 = 1 Thus, we have the following table giving two points on the line represented by the equation x + y = 4: Graph of the equation x + y = 4:
