What will happen if you execute the given code snippet ?
You are required to write a code that requests the user to enter three integer coefficients: a, b, and c in this order. Next, the user is requested to enter the equation degree: 1 for a linear equation and 2 for a quadratic equation. If the user enters an equation degree other than 1 or 2, the program must output Invalid. Based on the equation type, the program will process the coefficients and provide outputs as described below:
First Scenario: Linear Equation
When a linear equation is selected, the coefficient a is ignored and the equation format becomes:
y=bx+c
The program should check the slope of the line and accordingly print the values of the x-intercept, the y-intercept, and the line direction with respect to the x-axis each on a separate line. We have four possibilities:
Slope is positive (i.e. b > 0): x-intercept = −cb, y-intercept = c, direction is UpwardSlope is negative (i.e. b < 0): x-intercept = −cb, y-intercept = c, direction is DownwardSlope is zero (i.e. b = 0)…

After each selection, display the number of the employee to test. Display four employee numbers on each line. It is important to note that if testing is random, some employees will be tested multiple times, and others might never be tested. Run the application several times until you are confident that the selection is random. Save the file as DrugTests.java. My code is on the photo.
