The line x − y = 2 is on a coordinate plane and contains EF, which is one side of square EFGH. What is the slope of the line that contains FG?
I just need the steps on how to do it.

What is the multiplicative rate of change of the exponential function shown on the graph?

5,600 x 10^3 = a) 560 b) 5,000,600 c) 5,600,000 d) 56,000

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?
