Question

P(1.5,-1) and Q(-2.5,0) represents points in the coodinate plane. what is the length of PQ?

Answer 1

The length of PQ is 17 square units, or approximately 4.123 units.

Step-by-step explanation:

To find the length of PQ, we can use the distance formula. The distance formula is given by:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Let's plug in the coordinates of P (1.5, -1) and Q (-2.5, 0) into the formula:

d = sqrt((-2.5 - 1.5)^2 + (0 - (-1))^2)

d = sqrt((-4)^2 + (1)^2)

d = sqrt(16 + 1)

d = sqrt(17)

The length of PQ is 17 square units, or approximately 4.123 units.
