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,
![y = 16 + 0.5x](https://tex.z-dn.net/?f=y%20%3D%2016%20%2B%200.5x)
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,
![y = 16 + 0.5\times 0\\y = 16](https://tex.z-dn.net/?f=y%20%3D%2016%20%2B%200.5%5Ctimes%200%5C%5Cy%20%3D%2016)
But for x=0, y= 18, hence option 1 is not correct.
For option 2, put x = 5 in the given function,
![y = 16 + 0.5\times 5\\y = 18.5](https://tex.z-dn.net/?f=y%20%3D%2016%20%2B%200.5%5Ctimes%205%5C%5Cy%20%3D%2018.5)
But for x=5, y= 19.5, hence option 2 is not correct.
For option 3, put x = 8 in the given function,
![y = 16 + 0.5\times 8\\y = 20](https://tex.z-dn.net/?f=y%20%3D%2016%20%2B%200.5%5Ctimes%208%5C%5Cy%20%3D%2020)
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).
