Line a passes through (2,3) and (6,5) on a coordinate plane. Lines b, c, and d are defined by the ordered pairs below. Line b passes through (-2,1) and (4,4). Line c passes through (8,6) and (-1,-3). Line d passes through (-4,2) and (2,5). Determine whether lines b, c, and d form lines that intersect line a at no points, one point, or infinitely many points. Write the name of the point in the appropriate box.

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?
