Answer:
The length of segment JK is 5 ⇒ C
Step-by-step explanation:
The formula of the distance between the two points (x1, y1) and (x2, y2) is
d =
Let us use the formula above to solve the question
∵ Jk is a line segment
∵ J = (4, 8) and K = (-1, -2)
∴ x1 = 4 and y1 = 8
∴ x2 = -1 and y2 = -2
→ Substitute them in the formula above
∵ JK =
∴ JK =
∴ Jk =
∴ Jk =
→ Simplify the root
∵ 125 = 5 × 5 × 5
∴ = 5
∴ JK = 5
∴ The length of segment JK is 5
