Question

Write four solutions for each of the following equations: (ii) πx + y = 9

Answer 1

Step-by-step explanation:

The four solutions of the equation πx + y = 9 are (0, 9), (1, 9-π), (2, 9-2π) and (-1, 9+π). (0, 0) is the solution. (1, 1/4) is the solution. (4, 1) is the solution.

Answer 2

Answer:

(0, 9)(1, 9 − π),(2, 9 −2π) (−1, 9 + π)

Explanation:

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.
