To find the distance between two points \( A(x_1, y_1) \) and \( B(x_2, y_2) \), we can use the distance formula:
\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]
In this case, the coordinates of the points are:
- \( A(-3, 10) \) which gives \( x_1 = -3 \) and \( y_1 = 10 \)
- \( B(6, -7) \) which gives \( x_2 = 6 \) and \( y_2 = -7 \)
Now, we can plug in these values into the formula:
\[ d = \sqrt{(6 - (-3))^2 + (-7 - 10)^2} \]
Calculating the differences:
\[ 6 - (-3) = 6 + 3 = 9 \quad \text{and} \quad -7 - 10 = -17 \]
Now substitute these differences back into the formula:
\[ d = \sqrt{(9)^2 + (-17)^2} \]
Calculating the squares:
\[ d = \sqrt{81 + 289} \]
Adding them together:
\[ d = \sqrt{370} \]
Using a calculator to find the square root of \( 370 \):
\[ d \approx 19.2 \]
Rounding to the nearest tenth, the distance between points \( A \) and \( B \) is:
\[ \boxed{19.2} \]
