Step-by-step explanation:

The question is incomplete. However, I will solve using the following assumptions.

Job A:

y = 2x + 5

Job B

$\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {6} & {10} & {14} & {18} & {22} \ \end{array}$

The first step is to calculate the rate of Job B using:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Where:

(x_1,y_1) = (1,6)

(x_2,y_2) = (2,10)

So, we have:

$m = \frac{10 - 6}{2 - 1}$

$m = \frac{4}{1}$

m = 4

So, the hourly rate of job B is $4/hr

For Job A:

y = 2x + 5

A linear equation has the form:

y = mx + b

Where m is the rate

By comparison:

m = 2

So, the hourly rate of Job A is $2/hr

Comparing both rates, we can draw the following conclusions;

The hourly rate of Job A is greater than the hourly rate of Job BThe hourly rate of Job A is twice the hourly rate of Job B.
