Question

Transcribed Image Text:Write a program that asks the user to enter the coordinates of 4 points that draw
two different lines. The program has to display whether these two lines are parallel,
perpendicular, or neither according to the following formula:
Slope = 22-y1
x2-x1
If the slopes of both lines are equal, the two lines are parallel
If the product of both slopes is equal to -1, the 2 lines are perpendicular.
Otherwise, the two lines are neither parallel nor perpendicular.
Sample Run
Enter the 4 coordinates of first line: 5.7 8.9 7 7.8
Enter the 4 coordinates of second line: 5.7 7.6 3.5 8.9
The two lines are neither parallel nor perpendicular
