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: y2-y1 Slope = х2-х1 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 BUILD SUCCESSFUL (total time: 36 seconds)

Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

Question

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

Help Me With C Programming. At Lili's birthday party, there is a game arranged by Jojo as the host. The game is handing out a number of Y candies to a number of X people where all the sweets taste sweet except for the last one candy that tastes like rotten beans. The distribution of sweets will be sequential starting from position Z and if it passes the last position then the distribution of candy continues to the first position. Write down the person in the position of who will get the last candy. Format Input The first line of input is T, which is the number of test cases. The second row and the next number of T lines are X, Y, Z. X is the number of people who will be handed out candy. Y is the number of candies available. Z is the initial position of the person who will be handed out the candy. Format Output A string of "Case #N: " and a number that is the position of the person who got the last candy [Look at Image] In the sample above, for example, which is inputted in the…

A retail company assigns a $5000 store bonus if monthly sales are more than $100,000; otherwise a $500 store bonus is awarded. Additionally, they are doing away with the previous day off program and now using a percent of sales increase to determine if employees get individual bonuses. If sales increased by at least 4% then all employees get a $50 bonus. If they do not, then individual bonuses are 0. Step 7: The final step in completing the pseudocode is to call all the modules with the proper arguments. Complete the missing lines.
