Step-by-step explanation:
The question is incomplete. However, I will solve using the following assumptions.
Job A:
![y = 2x + 5](https://tex.z-dn.net/?f=y%20%3D%202x%20%2B%205)
Job B
![\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {6} & {10} & {14} & {18} & {22} \ \end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcccccc%7Dx%20%26%20%7B1%7D%20%26%20%7B2%7D%20%26%20%7B3%7D%20%26%20%7B4%7D%20%26%20%7B5%7D%20%5C%20%5C%5C%20y%20%26%20%7B6%7D%20%26%20%7B10%7D%20%26%20%7B14%7D%20%26%20%7B18%7D%20%26%20%7B22%7D%20%5C%20%5Cend%7Barray%7D)
The first step is to calculate the rate of Job B using:
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
Where:
![(x_1,y_1) = (1,6)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%20%3D%20%281%2C6%29)
![(x_2,y_2) = (2,10)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%20%3D%20%282%2C10%29)
So, we have:
![m = \frac{10 - 6}{2 - 1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B10%20-%206%7D%7B2%20-%201%7D)
![m = \frac{4}{1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B4%7D%7B1%7D)
![m = 4](https://tex.z-dn.net/?f=m%20%3D%204)
So, the hourly rate of job B is $4/hr
For Job A:
![y = 2x + 5](https://tex.z-dn.net/?f=y%20%3D%202x%20%2B%205)
A linear equation has the form:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Where m is the rate
By comparison:
![m = 2](https://tex.z-dn.net/?f=m%20%3D%202)
So, the hourly rate of Job A is $2/hr
Comparing both rates, we can draw the following conclusions;
- <em>The hourly rate of Job A is greater than the hourly rate of Job B</em>
- <em>The hourly rate of Job A is twice the hourly rate of Job B.</em>
