Which of the following points is a solution to the linear inequality y>1/9x−2/9?(1 point)

A: (0,−2/9)
B:(0,−4/9)
C: (0,−1/3)
D; 0,−1/9)

1 answer

To determine which of the points is a solution to the linear inequality \( y > \frac{1}{9}x - \frac{2}{9} \), we can substitute the x-coordinates of each point into the inequality and see if the corresponding y-coordinates satisfy it.

The inequality can be expressed for \( x = 0 \):

\[ y > \frac{1}{9}(0) - \frac{2}{9} \] \[ y > -\frac{2}{9} \]

Now we can check each point:

A: \( (0, -\frac{2}{9}) \)

  • Substitute \( y = -\frac{2}{9} \): \[ -\frac{2}{9} > -\frac{2}{9} \quad \text{(false)} \]

B: \( (0, -\frac{4}{9}) \)

  • Substitute \( y = -\frac{4}{9} \): \[ -\frac{4}{9} > -\frac{2}{9} \quad \text{(false)} \]

C: \( (0, -\frac{1}{3}) \)

  • Substitute \( y = -\frac{1}{3} \approx -\frac{3}{9} \): \[ -\frac{1}{3} > -\frac{2}{9} \quad \text{(false)} \]

D: \( (0, -\frac{1}{9}) \)

  • Substitute \( y = -\frac{1}{9} \): \[ -\frac{1}{9} > -\frac{2}{9} \quad \text{(true)} \]

The only point that satisfies the inequality is:

D: \( (0, -\frac{1}{9}) \).
