To find the horizontal and vertical changes between the points \((-1, -2)\) and \((5, 1)\), we can use the following formulas:
1. **Horizontal Change (Δx)**:
\[
\Delta x = x_2 - x_1
\]
where \((x_1, y_1) = (-1, -2)\) and \((x_2, y_2) = (5, 1)\).
Substituting the values:
\[
\Delta x = 5 - (-1) = 5 + 1 = 6
\]
2. **Vertical Change (Δy)**:
\[
\Delta y = y_2 - y_1
\]
Substituting the values:
\[
\Delta y = 1 - (-2) = 1 + 2 = 3
\]
Now, we can complete the statements:
The horizontal change between the points is **6**.
The vertical change between the points is **3**.

To find the slope of the line that passes through the points \((−1, −2)\) and \((5, 1)\), we can use the formula for the slope \(m\):
\[
m = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1}
\]
Substituting in the values from the points:
- \(y_1 = -2\)
- \(y_2 = 1\)
- \(x_1 = -1\)
- \(x_2 = 5\)
Calculating the differences:
\[
\Delta y = 1 - (-2) = 1 + 2 = 3
\]
\[
\Delta x = 5 - (-1) = 5 + 1 = 6
\]
Now substituting these values into the slope formula:
\[
m = \frac{3}{6} = \frac{1}{2}
\]
The slope of the line is **C. \( \frac{1}{2} \)**.
\[
m = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1}
\]
Substituting in the values from the points:
- \(y_1 = -2\)
- \(y_2 = 1\)
- \(x_1 = -1\)
- \(x_2 = 5\)
Calculating the differences:
\[
\Delta y = 1 - (-2) = 1 + 2 = 3
\]
\[
\Delta x = 5 - (-1) = 5 + 1 = 6
\]
Now substituting these values into the slope formula:
\[
m = \frac{3}{6} = \frac{1}{2}
\]
The slope of the line is **C. \( \frac{1}{2} \)**.

Bronze is a combination of copper and tin. A bronze tool with a 0.5 kg handle will have x kg of copper and y kg of tin with this equation: x−7y=0.5.
Can the tool have 3 kg of copper and 0.6 kg of tin?
First, let's substitute the appropriate numbers for the variables into our equation x−7y=0.5.
__ −7(__) = 0.5

To determine if the bronze tool can have 3 kg of copper and 0.6 kg of tin, we will substitute the values into the given equation \(x - 7y = 0.5\).
Here, \(x = 3\) (the amount of copper) and \(y = 0.6\) (the amount of tin).
The equation becomes:
\[
3 - 7(0.6) = 0.5
\]
Now calculate \(7 \times 0.6\):
\[
7 \times 0.6 = 4.2
\]
Now substitute this value back into the equation:
\[
3 - 4.2 = 0.5
\]
Calculating the left side:
\[
3 - 4.2 = -1.2
\]
Now we compare this result to the right side of the equation:
\[
-1.2 \neq 0.5
\]
Thus, the substitution does not satisfy the equation. Therefore, **the tool cannot have 3 kg of copper and 0.6 kg of tin**.
The final expression to fill in is:
**3 − 7(0.6) = 0.5**.
Here, \(x = 3\) (the amount of copper) and \(y = 0.6\) (the amount of tin).
The equation becomes:
\[
3 - 7(0.6) = 0.5
\]
Now calculate \(7 \times 0.6\):
\[
7 \times 0.6 = 4.2
\]
Now substitute this value back into the equation:
\[
3 - 4.2 = 0.5
\]
Calculating the left side:
\[
3 - 4.2 = -1.2
\]
Now we compare this result to the right side of the equation:
\[
-1.2 \neq 0.5
\]
Thus, the substitution does not satisfy the equation. Therefore, **the tool cannot have 3 kg of copper and 0.6 kg of tin**.
The final expression to fill in is:
**3 − 7(0.6) = 0.5**.

We will simplify the left side of the equation using the values we previously substituted:
We have:
\[
3 - 7(0.6)
\]
Now let's calculate \(7(0.6)\):
\[
7 \times 0.6 = 4.2
\]
Then, we substitute this value back into the equation:
\[
3 - 4.2
\]
Now, perform the subtraction:
\[
3 - 4.2 = -1.2
\]
So, when we write it out, we simplify the left side as:
\[
-1.2 = 0.5
\]
To clarify:
The simplified left side of the equation is **-1.2**. Therefore, we can write:
\[
-1.2 = 0.5
\]
This shows that the left side does not equal 0.5, confirming earlier that the tool cannot have 3 kg of copper and 0.6 kg of tin.
We have:
\[
3 - 7(0.6)

\[
3 - 4.2

So, when we write it out, we simplify the left side as:
\[
-1.2 = 0.5

To clarify:
The simplified left side of the equation is **-1.2**. Therefore, we can write:
