Question

What is the distance between (1,-4) and (1,18)?

Answer 1

Answer: 2

Step-by-step explanation:

Answer 2

The distance between two point in the cartesian coordinate system is:

d^2=(x2-x1)^2+(y2-y1)^2

d^2=(1-1)^2+(18--4)^2

d^2=0+484

d=22 units.

In this case we could have seen that the x coordinate did not change and just said the distance was 18--4=22 units, but that is rarely how you will solve these problems :P
