To solve the inequality \(\frac{7}{9}x \geq 1\), we will first isolate \(x\).
-
Multiply both sides of the inequality by \(9\) to eliminate the fraction:
\[ 7x \geq 9 \]
-
Next, divide both sides by \(7\):
\[ x \geq \frac{9}{7} \]
So the solution to the inequality is:
\[ x \geq \frac{9}{7} \]
Now, let's fill in the answer box in your choices:
The correct choice is: B. \(x \geq \frac{9}{7}\)
Graphing the Solution
To graph this solution on a number line:
- Draw a number line.
- Locate \(\frac{9}{7}\), which is approximately \(1.2857\).
- Since the inequality includes "greater than or equal to", draw a closed circle (or a filled dot) at \(\frac{9}{7}\).
- Shade the line to the right of this point, indicating that \(x\) can take any value greater than \(\frac{9}{7}\).
This graph represents all the values of \(x\) that satisfy the inequality.
