Answer:

4.1 units

Explanation:

You want the distance from A(3, 3) to line XZ, where segment AZ is shown as perpendicular to XZ. Point Z is (4, -1).

Distance

Since AZ is perpendicular to XZ, the desired distance is the length of AZ. That can be found using the distance formula:

d = √((x2 -x1)² +(y2 -y1)²)

d = √((4 -3)² +(-1 -3)²) = √(1² +(-4)²) = √17

d ≈ 4.1

The distance from A to XZ is about 4.1 units.
