To find the equation represented by the inequality that includes the points (0, -1) and (2, 0), we first determine the equation of the line that passes through these two points.
1. **Find the slope (m)** of the line:
\[
m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - (-1)}{2 - 0} = \frac{1}{2}
\]
2. **Use the point-slope form of the line**:
Using point (0, -1):
\[
y - y_1 = m(x - x_1) \Rightarrow y - (-1) = \frac{1}{2}(x - 0)
\]
Simplifying:
\[
y + 1 = \frac{1}{2}x \Rightarrow y = \frac{1}{2}x - 1
\]
3. **Convert to standard form**:
Rearranging gives us:
\[
-\frac{1}{2}x + y + 1 = 0 \Rightarrow x - 2y - 2 = 0 \Rightarrow x - 2y = 2
\]
4. **Create the inequality**:
To determine the correct inequality, test one of the points against this line. We can choose (0, 0):
\[
0 - 2(0) < 2 \Rightarrow 0 < 2 \quad \text{(true)}
\]
Therefore, the solution set is **above the line**.
Thus, the inequality is:
\[
x - 2y < 2
\]
So the final filled-in form is:
\[
1x + (-2)y < 2
\]
In summary, the solution set for the inequality is:
\[
x - 2y < 2
\]
1. **Find the slope (m)** of the line:
\[
m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - (-1)}{2 - 0} = \frac{1}{2}
\]
2. **Use the point-slope form of the line**:
Using point (0, -1):
\[
y - y_1 = m(x - x_1) \Rightarrow y - (-1) = \frac{1}{2}(x - 0)
\]
Simplifying:
\[
y + 1 = \frac{1}{2}x \Rightarrow y = \frac{1}{2}x - 1
\]
3. **Convert to standard form**:
Rearranging gives us:
\[
-\frac{1}{2}x + y + 1 = 0 \Rightarrow x - 2y - 2 = 0 \Rightarrow x - 2y = 2
\]

\]
In summary, the solution set for the inequality is:
\[
x - 2y < 2

I apologize for the oversight in my previous message. Let's reanalyze the information and correctly express the inequality in the form you're asking for.
Based on the points \( (0, -1) \) and \( (2, 0) \), we determined a line with the slope of \( \frac{1}{2} \).
To write this in the form you specified:
1. **Equation of the line**:
We calculated the line equation:
\[
y = \frac{1}{2}x - 1
\]
2. **To put this in standard form \( Ax + By < C \)**:
To move \(y\) to one side:
\[
-\frac{1}{2} x + y < -1
\]
3. **Multiply through by -2** (and reverse the inequality):
\[
x - 2y > 2
\]
or in the desired form:
\[
1x + (-2)y < 2
\]
This means the correct inequality in the format you wanted is:
\[
1x + (-2)y < 2
\]
Again, I apologize for the confusion earlier. Thank you for your patience!
