Question

distance between points: vertical or horizontal
point s is located at (9, -3). point t is located at (4, -3).
what is the distance from point s to point t?

Explanation:

Step1: Identify x - coordinates

The x - coordinate of point S is $x_1 = 9$ and of point T is $x_2 = 4$. The y - coordinates are the same ($y_1=y_2 = - 3$), so it's a horizontal distance.

Step2: Calculate distance

The distance $d$ between two points with the same y - coordinate is given by $d=\vert x_1 - x_2\vert$. So $d=\vert9 - 4\vert$.

Step3: Simplify expression

$\vert9 - 4\vert=\vert5\vert = 5$.
