Answer:
Proportional: Mike, a plumber charges $5 per hour for his service.
Non-proportional: Mike charges a initial cost of $10 plus $3 for each hours of service.
Step-by-step explanation:
Let us assume that Mike, a plumber charges $5 per hour for his service.
So, the number of hours (h) of service and the total charge (C) are proportional, which is
C(h) = 5h ....... (1)
If the condition changes like, Mike charges an initial cost of $10 plus $3 for each hour of service.
Here, the equation that models the situation is
C(h) = 10 + 3h .......... (2)
Now, relation (1) is non-proportional. (Answer)
D. Horizontal
It should be it if the direction of the line is containing those points
The given expression is a (A) linear expression.

What are linear expressions?</h3>
- A linear expression is an algebraic expression in which each term is a constant or a variable raised to the first power.
- To put it another way, none of the exponents may be greater than 1. x2 is a variable raised to the second power, whereas x is a variable raised to the first power.
- A constant is represented by the number 5.
- Reduce the equation as much as feasible to the form y = mx + b. Examine your equation for exponents.
- It is nonlinear if it has exponents. Your equation is linear if it contains no exponents.
- 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x - y + z = 3 are some instances of linear equations.
Therefore, the given expression is a (A) linear expression.
