The sum and product of coefficient of x and y are -1 and -2, respectively
How to determine the sum and product of coefficient of x and y
From the question, we have the following parameters that can be used in our computation:
The equation
Where, we have
y - 2x - 1 = 0
The coefficient of x and y are
x = -2
y = 1
So, we have
Sum = 1 - 2 = -1
Product = 1 * -2 = -2
Hence, the sum and product of coefficient of x and y are -1 and -2, respectively
