Question
Write four solutions for the following equation:
πx + y = 9
Solution
πx + y = 9
For x = 0,
π(0) + y = 9
⇒ y = 9
Therefore, (0, 9) is a solution of this equation.
For x = 1,
π(1) + y = 9
⇒ y = 9 − π
Therefore, (1, 9 − π) is a solution of this equation.
For x = 2,
π(2) + y = 9
⇒ y = 9 − 2π
Therefore, (2, 9 − 2π) is a solution of this equation.
For x = −1,
π(−1) + y = 9
⇒ y = 9 + π
Therefore, (−1, 9 + π) is a solution of this equation.
