Final answer:
The coordinates of point M, which lies on the line with K and L and divides KM in the ratio 1:m, are found using the section formula. By applying the pattern of movement from K to L to get to M, Option D (3,4) is the correct choice.
Step-by-step explanation:
To find the coordinates of point M on the line passing through K(2,3) and L(5,5), and given that L divides KM such that KL:LM is 1:m, we need to use the concept of section formula.
The section formula states that if a point (x, y) divides a line segment between two points (x1, y1) and (x2, y2) in the ratio m:n, then the coordinates of the point are given by:
x = (mx2 + nx1)/(m + n) and y = (my2 + ny1)/(m + n).
Using this formula for point L dividing the segment KM, we have:
x = (1*x + m*2)/(1 + m) and y = (1*y + m*3)/(1 + m).
Given the choices for coordinates of M, we can infer that the ratio m = 1, and we can use the formula to calculate x and y:
x = (1*5 + 1*2)/(1 + 1) = (5 + 2)/2 = 7/2 = 3.5
y = (1*5 + 1*3)/(1 + 1) = (5 + 3)/2 = 8/2 = 4
However, 3.5 is not an integer and none of the options match this result, which indicates that the correct ratio must lead us to one of the options given. We therefore observe the pattern of movement from K to L (3 units in x, 2 units in y) and apply it to get to M, looking for an option that fits this pattern. Option D, with coordinates (3,4), is the point M that satisfies this situation.
