Answer 1

To analyze the effect of the dilation with a scale factor of 5 and a center point at the origin (0,0), we need to apply the dilation transformation to points A, B, C, and D.

The dilation formula with center at the origin is: \[ (x', y') = (kx, ky) \] where \( k \) is the scale factor. In this case, \( k = 5 \).

Applying Dilation:

1. Point A (1, -5): \[ A' = (5 \cdot 1, 5 \cdot -5) = (5, -25) \]

2. Point B (4, -2): \[ B' = (5 \cdot 4, 5 \cdot -2) = (20, -10) \]

3. Point C (-1, 0): \[ C' = (5 \cdot -1, 5 \cdot 0) = (-5, 0) \]

4. Point D (2, 3): \[ D' = (5 \cdot 2, 5 \cdot 3) = (10, 15) \]

Conclusion:

So the resulting points after dilation are:

• \( A' (5, -25) \)
• \( B' (20, -10) \)
• \( C' (-5, 0) \)
• \( D' (10, 15) \)

The dilated lines will remain parallel because dilation preserves the orientation and parallelism of lines.

Correct Response:

After dilation, the lines are five units farther from the point of dilation. The resulting points are \( A' (5, -25) \), \( B' (20, -10) \), \( C' (-5, 0) \), and \( D' (10, 15) \). The dilated lines are parallel.
