Nts 6. A line passes through the points (0,7) and (6, 4). A second
line passes through the points (-8,.-9) and (4, 0).
A. Write the equation for each line and graph the system
of equations on the coordinate plane. Label each line
on your graph and show all of your work.
B. What is the solution to the system of equations?

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
