Darko found the distance between points a(3,-4) and b(-1,3) his work is shown below

We know that in two dimensional co-ordinate geometry, the distance,d, between any two points and is given by the formula:

We will use the above formula that Darko must have used to find the distance between the two points A(3,-4) and B(-1,3). In this case: and .

Thus, the distance,

Therefore, the distance between the given points A(3,-4) and B(-1,3) is: or 8.06 (approx).

the correct answer is 45x

9×5=45 then add the x
