1. Problem Description

Triangle LMNLMN is dilated by a scale factor of 14\frac{1}{4} centered at the origin. We are asked to find the coordinates of the resulting triangle.

2. Solution Steps

First, we need to find the coordinates of the vertices of the original triangle LMNLMN from the graph.
LL appears to be at (4,8)(-4, 8).
MM appears to be at (6,4)(6, 4).
NN appears to be at (8,0)(-8, 0).
Next, we will apply the dilation factor of 14\frac{1}{4} to each coordinate of each vertex.
To dilate a point (x,y)(x, y) by a scale factor kk centered at the origin, the new point is (kx,ky)(kx, ky).
For L(4,8)L(-4, 8), the new coordinates LL' are:
L=(14×4,14×8)=(1,2)L' = (\frac{1}{4} \times -4, \frac{1}{4} \times 8) = (-1, 2).
For M(6,4)M(6, 4), the new coordinates MM' are:
M=(14×6,14×4)=(64,1)=(32,1)=(1.5,1)M' = (\frac{1}{4} \times 6, \frac{1}{4} \times 4) = (\frac{6}{4}, 1) = (\frac{3}{2}, 1) = (1.5, 1).
For N(8,0)N(-8, 0), the new coordinates NN' are:
N=(14×8,14×0)=(2,0)N' = (\frac{1}{4} \times -8, \frac{1}{4} \times 0) = (-2, 0).

3. Final Answer

The coordinates of the resulting triangle are:
L(1,2)L'(-1, 2)
M(1.5,1)M'(1.5, 1)
N(2,0)N'(-2, 0)
