Question

Find the length of PQ. The endpoints are P(-2,-1) and Q(2,4)

Answer 1

Morgy, this is the solution:

Point P = (-2, -1)

Point Q = (2, 4)

Let's use the formula to calculate the distance, this way:

d = √(2 - -2)² + (4 - -1)²

d = √4² + 5²

d = √16 + 25

d = √41

d = 6.403

In consequence, the lenght of PQ is 6.403 units
