Question

12. Find the distance between the points (-15, 3) and (-9,8).

OO
OA. V 697 units
B. V 601 units
O C. V 61 units
OD. V 157 units

Answer 1

option c =
`√(61)`

Explanation:

we know the distance between two points:

d=
`\sqrt{(x2-x1)^(2) + (y2-y1^(2)}`

we have:

(-15, 3) and (-9,8)

d=
`\sqrt{(-9+15)^(2)+(8-3)^(2)}`

d=
`\sqrt{6^(2) + 5^(2) }`

d=
`√(36+25)`

d=
`√(61)`
