Given that:
- The consumers will demand 46 units when the price of a product is $39.
- The consumers will demand $58 units when the price is $24.
1. You need to remember the Slope-Intercept Form of the equation of a line:

Where "m" is the slope of the line and "b" is the y-intercept.
2. In order to find the slope of the line, you can use this formula:

Where these two points are on the line:

In this case, knowing that:

Then, you can identify these two points:

Therefore, you can set up that:

Hence, substituting values into the formula, you get:

3. In order to find the value of "b", you can follow these steps:
- Substitute one of the points and the slope, into this equation:

Then:

- Solve for "b":

4. Knowing the slope and the y-intercept, you can write the following Demand Function:

Hence, the answer is:
