Question

1. Find the distance between the two points in simplest exact form. (-1,4) and (-1,-4)

Answer 1

Use the formula: sqrt[(x2-x1)^2+(y2-y1)^2]
x1 and x2 are the x-coordinates and y1 and y2 are the y-coordinates.

Plug in the values: sqrt[(-1+1)^2+(-4-4)^2]
Simplify the squares: sqrt(64)
Evaluate sqrt(64) = 8

Answer is 8.
