Question

Write four solutions for the following equation:

πx + y = 9

Answer 1

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.
