Answer:
y = 2x + 0 or y = 2x
Step-by-step explanation:
use slope-intercept form
12 - 10 = 2
6 - 5 = 1
m value = 2/1 = 2
y=2x+b
to find b plug one of the points in for x and y
Example: 10 = 2(5) + b
solve equation
10 = 10 + b
subtract 10 from both sides
0 = b
Equation of line equals y=2x+0 or simply just y=2x

Solution
Problem 1:
- Kelsie pays a one-time fee for the equipment of $5.00. This is a fixed cost that never changes and is paid just once.
- Kelsie pays $18.99 for each hour (h). This means that
For 1 hour, Kelsie pays $18.99 * 1 = $18.99
For 2 hours, Kelsie pays $18.99 * 2
For 3 hours, Kelsie pays $18.99 * 3
And so on...
- We can generalize this for h hours. That is,
For h hours, Kelsie pays $18.99 * h
- Thus, Kelsie pays $18.99h after h hours separate from the initial fee of $5.00.
- Thus, her total cost would be the addition of the flat fee of $5.00 and the cost of playing for h hours. That is:
Problem 2:
- Jayson pays $35 per hour with no initial flat fee.
- Following the same logic as in the case of Kelsie, we can write the total cost incurred by Jayson after h hours is:
