Answer: 8 units

Step-by-step explanation:

To find the distance between 2 points, we want to use the formula $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ . Since we are given the 2 points, all we have to do is plug them in.

$d=\sqrt{(7-(-1))^2+(8-8)^2}$ [parenthesis]

$d=\sqrt{(8)^2+(0)^2}$ [exponent]

$d=\sqrt{64+0}$ [add]

$d=\sqrt{64}$ [square root]

$d=8$

Now, we know the distance is 8 units.

Home is located at the point (-5, 5)

The park is located at the point (-2, 3)

Apply the distance formula

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-5-(-2))^2 + (5-3)^2}\\\\d = \sqrt{(-5+2)^2 + (5-3)^2}\\\\d = \sqrt{(-3)^2 + (2)^2}\\\\d = \sqrt{9 + 4}\\\\d = \sqrt{13}\\\\d \approx 3.6055513\\\\$

When rounding to the nearest whole number, we get 4. This is the approximate distance (in blocks) from home to the park. I'm not sure why "4 blocks" isn't listed as a possible distance, so there may be a typo somewhere.

You'll apply this idea to the other pairs of points to find the other distances.
