Option 3 is the correct answer. The missing values of (x, y) is (8, 20).
<h3>How do you find out the values?</h3>Given that the function is,
The function is a linear equation that can be solved graphically. The values of both variables x and y can be found on different points along with the straight-line graph.
Also, for every value of x, there is a corresponding value of y.
For the given options, we put the values of x to find the corresponding value of y.
For option 1, put x = 0 in the given function,
But for x=0, y= 18, hence option 1 is not correct.
For option 2, put x = 5 in the given function,
But for x=5, y= 19.5, hence option 2 is not correct.
For option 3, put x = 8 in the given function,
But for x=8, y= 20, hence option 3 is the correct answer.
Hence we can conclude that option 3 is the correct answer. The missing values of (x, y) is (8, 20).

Answer:
D = 0; one real root
Step-by-step explanation:
Discriminant Formula:
First, arrange the expression or equation in ax^2+bx+c = 0.
Add both sides by 9.
Compare the coefficients so we can substitute in the formula.
- a = 1
- b = 6
- c = 9
Substitute a = 1, b = 6 and c = 9 in the formula.
Since D = 0, the type of solution is one real root.
