The line graph shown below is of the amount of money astudent earns at a part time job, per hour. What is the students wage rate
xeze [42]

1) The two lines are <em>perpendicular</em>. (Correct choice: True)

2) The slope of the <em>linear</em> function is $ 10 per hour. (Correct choice: A)

<h3>How to analyze and interpret linear functions</h3>

Herein we must understand and analyze <em>linear</em> functions to find all required information from two exercises. The first exercise asks us to prove if the two lines seen are <em>perpendicular</em> and the second exercise asks us to calculate and interpret the slope of the <em>linear</em> function. Now we proceed to resolve each point:

Exercise 1

If the two lines are perpendicular, then the product of the two slopes must be equal to - 1. The value of slope can be found by <em>secant line</em> formula:

m · m' = - 1

[(1 - 2) / [0 - (-1)]] · [[-1 - (- 2)] / (1 - 0)]

(- 1 / 1) · (1 / 1)

- 1

The two lines are <em>perpendicular</em>. (Correct choice: True)

Exercise 2

In this part we must determine the rate of change of wage in time, in monetary units per time, which can be found by again by the <em>secant line</em> formula:

m = ($ 10 - $ 0) / (1 h - 0 h)

m = $ 10 per hour

The slope of the <em>linear</em> function is $ 10 per hour. (Correct choice: A)

Which of the following coordinates belong in the box?
Lera25 [3.4K]
Since the distance from the two known coordinates are known, you can find the slope of the line (for lack of a better word) to work backwards. there is a +5 unit gap between -21 and -16, so the next number would be -26. So, without havint to do any more work, the answer is B.
