Hey! i’ll give brainliest please help!

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined

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.
