Find the distance between the points (12,9) and (0,4).
J. 15 units
K. 14 units
L. 13 units
To find the distance between two points, we can use the distance formula:
d = √((x2-x1)^2 + (y2-y1)^2)
In this case, the x-coordinate of the first point is 12, the y-coordinate of the first point is 9, the x-coordinate of the second point is 0, and the y-coordinate of the second point is 4.
Using the distance formula, we have:
d = √((0-12)^2 + (4-9)^2)
= √((-12)^2 + (-5)^2)
= √(144 + 25)
= √169
= 13.
Therefore, the distance between the points (12,9) and (0,4) is 13 units.
