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).

Answer:
5.2 seconds
Step-by-step explanation:
Traveling straight down: 90 * 3.5 = 315 feet down
Traveling up: 30 * 2.2= 66
315-66= 249
249/48= 5.1875 seconds
5.2 seconds <- rounded
Your answer is correct !!!!
