Question

Two weeks ago Audrey earned $84 for 7 hours of work. This week, she earned 132 for 11 hours of work. Find the numerical value of the slope of the line.

Answer 1

The slope is (132-84)/(11-7)=48/4=$12 per hour.

Answer 2

Answer: The required numerical value of the slope of the line is 12.

Step-by-step explanation: Given that two weeks ago Audrey earned $84 for 7 hours of work. This week, she earned 132 for 11 hours of work.

We are to find the numerical value of the slope of the line.

Let x represents the number of hours of work and y represents the corresponding earning.

Then, two points on the line will be (x, y) = (7, 84) and (11, 132).

We know that

the slope of a line passing through the points (a, b) and (c, d) is given by

`m=(d-b)/(c-a).`

Therefore, the slope of the given line is

`m=(132-84)/(11-7)=(48)/(4)=12.`

Thus, the required numerical value of the slope of the line is 12.
