Final answer:
The lines are neither parallel nor perpendicular.
Step-by-step explanation:
The relationship between the line containing the points (2, 3) and (-4, 5) and the line containing the points (1, -1) and (-2, 0) can be determined by finding the slopes of the lines.
To find the slope of a line, you can use the formula: slope = (y2 - y1) / (x2 - x1).
By calculating the slopes of both lines, we can determine that they are neither parallel nor perpendicular to each other.
