To find the distance between your house and the pool on a coordinate plane, we can use the distance formula. However, since both points have the same x-coordinate (2), we can find the distance by subtracting the y-coordinates.
The coordinates of the pool are (2, 20) and the coordinates of your house are (2, 18).
Calculating the distance:
\[ \text{Distance} = |y_2 - y_1| = |20 - 18| = 2 \text{ miles} \]
Thus, your house is 2 miles from the pool.
