Answer:
import java.util.Scanner;
// Needed for the Scanner class This program calculates the user's gross pay.
public class Pay {
public static void main(String[] args) {
// Create a Scanner object to read from the keyboard.
Scanner keyboard = new Scanner(System.in);
// Identifier declarations
double hours;
// Number of hours worked
double rate;
// Hourly pay rate
double pay;
// Gross pay
// Display prompts and get input.
System.out.print("How many hours did you work? ");
hours = keyboard.nextDouble();
System.out.print("How much are you paid per hour? ");
rate = keyboard.nextDouble();
// Perform the calculations.
if (hours <= 40) {
pay = hours * rate;
}
else
{
pay = (hours - 40) - (1.5 * rate) + 40 - rate;
}
// Display results.
System.out.println("You earned $" + pay);
}
}
Explanation:
To make a horizontal line in mathematics you require some sort of constant function. Where no matter the input x the output y will always equal to a certain number n.
For eg. consider n = 2. Hence the graph of line has an equation of y = n making it always intercept in (x, n). As x increases the y is the same therefore the horizontal infinite line emerges.
So to plot or code this kind of program you need to have the same values of y therefore y is a constant function.
Hope this helps.
