Number 14 find the distance between the two points

The distance is 6.325.

When we have two points and we want to find the distance from these two, we can use a formula developed, known as the distance formula.

Let your two points be (x₁, y₁) and (x₂, y₂).
The distance between these two points are:

d = √[(x₁ - x₂)² + (y₁ - y₂)²]

Following this, we can say that:
d = √[(1 - (-1))² + (3 - (-3))²]
d = √[2² + 6²]
d = √(4 + 36)
d = √40

d = 2√10
