Answer:
(80, 120)
Step-by-step explanation:
y - 40 + y = 200
2y = 240
y = 120
x = 120 - 40
x = 80

The desired linear functions are given as follows:
a) x = a.
b) y = b.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
A vertical line has undetermined slope, hence it is defined by x = a, containing point (a,b).
A horizontal line has slope of 0, hence it is defined by y = b, containing point (a,b).
