Question

find the distance between the pair of points. a(0,4), b(0,15) d = (simplify your answer. type an exact answer, using radicals as needed.)

Explanation:

Step1: Identify the coordinates

Points are \( A(0, 4) \) and \( B(0, 15) \). So \( x_1 = 0, y_1 = 4, x_2 = 0, y_2 = 15 \).

Step2: Use distance formula (vertical line)

Since \( x_1 = x_2 \), distance \( d = |y_2 - y_1| \).
\( d = |15 - 4| = 11 \)

Answer:

\( 11 \)
