Another lines and intercepts question me! : (

Find the slope and the y-intercept if there's one and the equation of the line given these two points( 3, 2) and( 3, -4)

I’m stuck on this equation, anyone got the answer?

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.
