Q:
# The table shows the amount Maggie earns for various numbers of hours she babysits. Graph the data. Then find the slope of the line. Explain what the slope represents. Number of hours, 1, 2, 3, 4, and earnings $, 8, 16, 24, 32.

Accepted Solution

A:

Answer: The required slope of the line is 8 and it represents that the earning of Maggie per hour is $8.Step-by-step explanation: Given that the following table shows the amount Maggie earns for various numbers of hours she babysits :Number of hours 1 2 3 4Earnings 8 16 24 32We are to graph the data and to find the slope of the line. From the table, we note that the points on the line representing the data are (1, 8), (2, 16), (3, 24) and (4, 32).These points are plotted on the co-ordinate plane and its graph is shown on the attached figure below.Now, the slope of a line passing through the points (a, b) and (c, d) is given by[tex]m=\dfrac{d-b}{c-a}.[/tex]So, the slope of the line representing the data is [tex]m=\dfrac{16-8}{2-1}=8.[/tex]Thus, the required slope of the line is 8 and it represents that the earning of Maggie per hour is $8.
