A.)Would the equation be sine or cosine if the situation was someone being on a roller coaster that starts 15 ft above ground level, goes up to 45 feet above ground level, and goes down 20 feet under ground level? b.) What would the equation be? ford monition and the terminal is in the third quadrant​

A) The slope of the line would be 6. This is found by using the point slope formula; (y2-y1)/(x2-x1). It would be shown as (10-(-2))/(4-6) which is simplified to 6.

B) The point slope form equation is y=mx+b so we need to find the y intercept. We do this by plugging in all the numbers we have so far and a point we were given in the beginning. If we plug everthing in it would look something like this -2=6(4)+b. When we solve, b=-26. Since its asking for us to write it in point-slope form, it would be like y+2=6(x-4). The point-slope form is y-y1=m(x-x1)

C) The equation of the line in slope intercept form is y=6x-26. All work is shown previously.
