Question

Help asap will give 30 points.

Point A is at (3, 1) and Point B is at (3, 8). The distance from Point A to Point B is

Answer 1

Answer: 7 units

=========================================================

Short explanation:

Plot the points (3,1) and (3,8). Note how they line up vertically. Count the number of vertical spaces between them and you should get 7 units. This only works if the points line up horizontally or vertically.

Or you could subtract the y coordinates to get 8-1 = 7, which is an alternative to graphing and counting the spaces. This is preferred if there is a very large gap.

----------------------------

Longer method:

Use the distance formula with (x1,y1) = (3,1) and (x2,y2) = (3,8)

`d = √((x_1 - x_2)^2 + (y_1 - y_2)^2)\\\\d = √((3-3)^2 + (1-8)^2)\\\\d = √((0)^2 + (-7)^2)\\\\d = √(0 + 49)\\\\d = √(49)\\\\d = 7\\\\`
