Question

How do you find the distance between (-4,1) and (3,-1)?

Answer 1

7.2801....

Explanation:

This is basically Pythagoras' therom just on a graph. As the shortest distance between these points will be straight and you can make a right-angled triangle from these co-ordinates

So you fin the difference in the x co-ordinates (3--4=7) and the difference in the y co-ordinates (1--1=2)

These are a and b in the equation `a^2+b^2=c^2`

So `7^2+2^2=53`
distance between (-4,1) and (3,-1) = `sqrt53=7.2801...`
