To represent the inequality \( 25 - 4x > -7 \) on a number line, let's first solve it.

### Step 1: Solve for \( x \)
We begin by isolating \( x \).

\[
25 - 4x > -7
\]

Subtract 25 from both sides:

\[
-4x > -7 - 25
\]

\[
-4x > -32
\]

Now, divide both sides by -4. When dividing by a negative number, remember to flip the inequality sign:

\[
x < \frac{-32}{-4}
\]

\[
x < 8
\]

### Step 2: Represent \( x < 8 \) on a number line
- Draw a number line.
- Mark the point \( 8 \) on it.
- Since the inequality is strict (i.e., \( < \)), we will use an open circle at \( 8 \) to indicate that \( 8 \) is not included.
- Shade all numbers to the left of 8 to represent \( x < 8 \).
