What is the distance between the points (-1, 4) and (2, 5)?

Question

anonymous · Answer

do you know the distance formula?

anonymous · Answer

Janett, it may seem unrelated at first, but let me ask, how comfortable are you with the pythagorean theorem?

anonymous · Answer

@aussy123 i dont 
and @SmoothMath i know how to do the pythsgoren theorem

anonymous · Answer

You use the distance formula.  You have two points which are of the form (x1, y1) and (x2, y2), so distance = sqrt[(x1-x2)^2 + (y1-y2)^2]   x1=-1, y1=4, x2=2, y2=5

Alright, Janett, let me teach you how to use the Pythagorean formula to find the distance =)

Here are the two points we're talking about:
|dw:1351608055165:dw|

anonymous · Answer

The first thing you need to do is draw a right triangle. The horizontal side will be the x-distance, and the vertical side will be the y-distance.

@SmoothMath ok i see it

anonymous · Answer

Now, connect the two points with a straight line, that is the distance between the two points:
|dw:1351608244387:dw|
