5seconds after contacting the air traffic controller the airplane is at an altitude of 1800 feet. 20 seconds after cantacting the air traffic controller he is at an altitude of 1350 feet. what is the equation is point-slope form. explain how to find it. i need .

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?

If a line is defined by the equation y = 5x + 2, what is the slope?

I’m really confused and need your assist me with this question i’ve never been taught
