What is the distance between #(15,-4)# and #(7,5)#?
See a solution process below:
The formula for calculating the distance between two points is:
Substituting the values from the points in the problem gives:
It might not seem like it, but this question just invooves simple Pythagorus on a graph. Instead of getting the two lengths of the known sides, it has to be worked out by finding the length.
However, this is super easy, just fin the change in
To get from 15
To get from -4
Now we have a right-angled triangle of lengths 8, 9, and
To find the length of
We add our values in to get
