Question

What is the distance between (1, 9) & (1,-4)? Round to the nearest tenth if necessary.

Answer 1

Step-by-step explanation:

√(1-1)+((-4)-9)

√0+199

√199

14.106735979665885

14.106 approx...

Answer 2

Answer: 5

Step-by-step explanation:

Coordinate distance formula is:

distance of coordinate= $(x2-x1)^2-(y2-y1)^2$

Here lets take C (1,9) D (1,-4)

Therefore:

$1:x1\\9:y1\\1:x2\\-4:y2$

Put the coordinates in the equation.
