Answer:

Parallel

Step-by-step explanation:

<u>Given points</u>

P(-9, -4), Q(-7, -1), R(-2,5), S(-6, -1)

<u>Finding slopes of PQ and RS using slope formula</u>

m = (y2 - y1)/(x2 - x1)

<u>Slope of line PQ</u>

m = (-1 - (-4))/(-7 - (-9)) = 3/2

<u>Slope of line RS</u>

m = (-1 - 5)/(-6 - (-2)) = -6 / -4 = 3/2

Slopes are same, therefore lines are parallel

The relationship between income (I), in dollars, and the time (h), in hours, for 2 different jobs is represented. Compare the ho

Andrews [41]

Answer:

See Explanation

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;

<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>
